Some people with type 1 diabetes experience some insulin resistance and higher blood glucose levels with hormonal birth control, such as the pill, hormonal coil, implant, or vaginal ring.

Some may see blood sugars fluctuate at first but are then able to stabilise them with a slight change to their insulin treatment. As with menstruation and menopause , hormones affect everyone differently and monitoring your blood sugar will help you to identify side effects.

Using a continuous glucose monitor or flash glucose monitor can help you keep your blood glucose in range. The two main types of contraceptive pill are a combined oestrogen and progesterone pill and a progesterone-only pill. Both contain hormones that, when taken correctly, prevent pregnancy.

Some people with type 1 diabetes will not encounter any side effects when taking the pill. Others may find that they become more resistant to insulin and have nausea or headaches.

Lower-dose contraceptive pills are less likely to impact your blood glucose. A combination pill that uses synthetic oestrogen and a type of progesterone hormone called norgestimate is often recommended for people with type 1 diabetes.

The NHS advises that the combined pill might not be suitable for anyone who has diabetes with complications or who has lived with the condition for more than 20 years.

In the past, people with type 1 diabetes have been advised to avoid taking the pill because of an effect on blood glucose and a risk of heart disease. Changes to the level of hormones in the newer generation of birth control pills means that these risks have greatly reduced, although you should still ask your GP about possible risks.

You will need to monitor your blood glucose levels and keep an eye on how you are feeling in the first few months of taking the pill. If you have any doubts about managing your insulin needs, talk to your Diabetes Healthcare Team.

The coil or IUD is a small T-shaped plastic and sometimes plastic and copper device that is placed inside the uterus by a healthcare professional. They are highly effective if fitted correctly but both have a small risk of infection after fitting.

You can ask your GP or Practice Nurse to check it after a few weeks to make sure that everything is ok. The coil is often a better contraception option for people who have type 1 complications affecting the eyes or kidneys.

Speak to your Diabetes Healthcare Team about whether this might be a good option for you. The non-hormonal option — a copper coil — releases copper in the uterus to protect you against pregnancy and can last for five to ten years.

In the first few months after being fitted, you might experience heavier, longer or more painful periods. Because hormones are not being released, there are none of the usual side effects like headaches and breast tenderness.

Copper coils rarely affect blood glucose levels. A hormonal coil Mirena releases the hormone progesterone to stop you getting pregnant and lasts for three to five years. It can be used by people who may not be able to take the combined pill.

It may not be considered a suitable option if you have had cancer, liver disease or heart disease. With a hormonal coil, you may have shorter or lighter periods, or they may stop altogether which might help if you usually see blood glucose changes while on your period.

Some people experience side effects such as headaches and breast tenderness but these usually settle in time. The progesterone can impact on blood glucose so, as with any new treatment, you will need to monitor your levels on an ongoing basis. A vaginal ring NuvaRing is a small dome-shaped plastic ring that is placed into your vagina and which releases hormones — oestrogen and progestogen — to prevent pregnancy.

There are a number of people for whom it may not be suitable. This includes people with type 1 diabetes who have experienced complications like kidney, eye, nerve or blood vessel damage.

Generally, because the hormones in the ring are absorbed directly into the vagina, there is little or no impact on blood glucose management. Nexplanon, or Implanon, is a contraceptive implant that is placed under the skin of the upper arm and releases the hormone progestogen into the bloodstream to prevent pregnancy.

It can be a good option for anyone who might not be able to use contraception containing oestrogen. Implants are largely thought safe for people with type 1 diabetes to use but, as with most other birth control methods, their effects can be different for everyone.

Keep monitoring your blood glucose after insertion to see how your levels react to the progestogen. Some medicines can make the implant less effective so speak to your GP or practice nurse first if you are on any other treatment or if you have a history of heart disease, stroke, liver disease or breast cancer.

It lasts for two or three months again, depending on which injection you have and can be an option for anyone who cannot use contraception containing oestrogen. Because of the hormone release, there is a higher risk of weight gain which could lead to being more resistant to insulin.

People with type 1 diabetes might be advised by their healthcare professional to start on a lower dose and to monitor blood glucose levels closely. There are two types of condom — external worn on the penis and internal worn inside the vagina. They are a good choice for people with type 1 because they do not contain hormones and therefore have no effect on blood glucose.

The unadjusted cross-sectional association between current OC use and these end points, obtained by combining the data from the 3 exam years, is shown in Table 2.

Persons with diabetes were excluded from the analyses of glucose and insulin but examined in the analysis of diabetes. Current use of OCs was associated with lower concurrent fasting glucose levels but was not associated with lower concurrent fasting insulin levels.

Current use of OCs was also associated with a lower unadjusted odds of diabetes by self-report and hyperinsulinemia. These associations were similar when diabetes was defined by glucose level or medication use instead of by self-report.

The adjusted cross-sectional association between current use of OCs and these end points from the combined data are also shown in Table 2. The cross-sectional association between current use of OCs and fasting insulin levels changed with the addition of covariates, so that current use of OCs was associated with elevated fasting insulin levels.

Adjusting for all covariates, including mean arterial pressure, HDL levels, and triglyceride levels, resulted in statistically significant associations between current use of OCs and decreased fasting glucose, current use of OCs and decreased odds of diabetes, and current use of OCs and increased insulin levels.

The results did not change significantly when an interaction term between race and BMI or between age and OC was introduced into the model. Excluding participants taking medication for diabetes, blood pressure, or lipid reduction or stratification by BMI and waist-to-hip ratio did not reveal any significant differences results not shown.

Analysis of African-Americans and whites separately did not reveal significant differences between races. Therefore, results in African-Americans are similar to those reported in Table 2 , although CIs widened due to reduced sample size.

In African-American women, current use of OCs was associated with lower fasting glucose levels in unadjusted analyses [—3. Similarly, in African-American women, current use of OCs was associated with lower odds of diabetes before adjustment [odds ratio 0.

We found that current use of OCs was associated with lower glucose levels in a racially diverse sample of young women. Current use of OCs had an inconsistent association with insulin levels, with no association before adjustment but an association with higher insulin levels after adjustment for covariates.

In cross-sectional analysis, current use of OCs was associated with a lower odds of diabetes. The association between use of OCs and incident diabetes was not significant in longitudinal analysis, although the number of women with incident diabetes at year 10 was low.

To our knowledge, this analysis of current use of OCs and glucose levels, insulin levels, and diabetes involves the largest numbers of young African-American women to date.

In the face of a type 2 diabetes epidemic, which disproportionately affects minorities and increasingly affects young women, the possibility that use of OCs may be associated with a lower odds of diabetes may have important clinical implications, although this finding must be replicated.

Also, our results on glucose and insulin levels are somewhat reassuring, especially because previous analyses of current use of OCs and glucose and insulin levels have found either no significant association 8 , 9 or an association with higher levels of glucose 20 , 21 and insulin In the Bogalusa Heart Study 9 , current use of OCs was not related to glucose or insulin levels in a cross-sectional analysis.

However, the study was only able to adjust for age and subscapular skin thickness, and individuals with diabetes were not explicitly excluded. In a cross-sectional analysis of the Cardiovascular Risk in Young Finns study, Porkka et al.

Other studies of OCs found that current use of combination OCs was associated with significantly higher glucose levels 20 , 21 and insulin responses 21 compared with nonuse.

Our results may have differed because of our ability to adjust for additional variables. It is also possible that our study subjects included a larger proportion of women with polycystic ovary disease, as CARDIA participants were more obese; in women with polycystic ovary disease, OCs may suppress follicle-stimulating hormone and luteinizing hormone, in turn suppressing ovarian androgen secretion and thereby decreasing insulin resistance and glucose levels Estrogen may lead to decreased fasting glucose levels by depressing hepatic glucose production 23 ; estrogen may act as a glucagon antagonist by increasing the molar ratio of insulin to glucagon in the hepatic portal vein, reducing the basal activity of phosphoenol pyruvate carboxykinase, the key gluconeogenic enzyme In postmenopausal women, estrogen replacement has been linked with decreased hyperandrogenicity and improved glucose homeostasis 25 , The association between OCs and insulin has been less consistent, perhaps partially due to increased variability in insulin levels OCs have been associated with insulin resistance during intravenous glucose tolerance testing 28 , determined primarily by estrogen effect and not associated with progestagenicity and androgenicity.

However, the association between OCs and fasting insulin is believed to depend largely on the dose and type of progestogen, with hyperinsulinemic responses most evident with levonorgestrel 23 and less common with norethindrone or desogestrel 5 , 6.

Few of the women in our study were using OCs containing levonorgestrel at year 10, but it is possible that women may have had different responses to OCs depending on their insulin levels before initiation of OCs; a trial of hormone replacement in postmenopausal women has found that insulin and glucose effects were most pronounced among women who had elevated levels of pretreatment fasting insulin and postprandial glucose It is possible that women in our study had higher fasting insulin levels, which in turn may have been associated with increased 2-h glucose levels, but were also associated with decreased fasting glucose through hepatic glucose suppression.

When we examined the cross-sectional association between current use of OCs and the presence of diabetes, current use of OCs seemed to be related to lower diabetes risk in both African-American and white women, although CIs were wide.

Prospective analyses of the Nurses Health Study, a population that was predominantly white and older at enrollment, found no association between current use of OCs and incident diabetes or former use of OCs and incident diabetes after adjustment for multiple covariates and after analysis by formulation 10 , Our contradictory findings may be partially explained by our different study design; we examined concurrent diagnosis of diabetes rather than incident diagnosis.

It is possible that patients with the diagnosis of diabetes were prescribed OCs less often than individuals without diabetes, but we excluded persons with diabetes from the analysis of glucose levels and still found a negative association between use of OCs and fasting glucose levels.

Although possible surveillance bias may have existed in our analysis i. There are several limitations that must be considered in interpreting our findings. Our study is primarily cross-sectional, and it is unknown whether OCs were avoided in women with diabetes or whether OC use itself influenced glucose and diabetes development.

However, we were concerned with the effect of OC use on concurrent glucose and insulin levels, and longitudinal analyses may have been limited by misclassification of OC status. Information on side effects of OCs was not collected, and it is possible that side effects would occur in women more likely to develop glucose tolerance.

Because women in the CARDIA study primarily used first-generation OCs, we were unable to assess for the effect of different types of progestins; as previously mentioned, second-generation progestins may be associated with a higher risk than third-generation progestins 5 , 6 , We were unable to assess whether patients had type 1 or type 2 diabetes; this is an unpredictable source of bias but may explain the failure to find a relationship between use of OCs and incident diabetes at year Another unpredictable source of bias is that women with endocrinopathies, e.

We were unable to adjust for a diagnosis of gestational diabetes. It is possible that patients with this diagnosis would have been prescribed OCs less often but are also more likely to develop diabetes, although the importance of birth control is believed to outweigh the diabetogenic potential of OCs Furthermore, gestational diabetes may be a precursor of type 2 diabetes, and therefore adjustment would have falsely lowered the association between OCs and glucose levels.

Finally, it is possible that other unmeasured confounders affect use of OCs and also affect development of diabetes.

In conclusion, current use of OCs does not seem to be associated with impaired carbohydrate metabolism or increased risk of diabetes in young women. On the contrary, OCs are associated with significantly lower glucose levels and may be associated with lower odds of diabetes in young African-American and white women.

OCs may be associated with higher insulin levels, but the effect on glucose levels is difficult to ascertain. Although the relative influence of OCs on diabetes risk may be significantly less than that of other risk factors, use of OCs represents a modifiable exposure with the significant health benefit of birth control.

The association between lower glucose levels and OCs could be important, as women develop diabetes at a progressively younger age. In addition, although the findings on diabetes must be replicated, the potential significance is large considering the numbers of women using OCs and the increasing incidence of type 2 diabetes.

Further examination of the physiology of OCs and carbohydrate metabolism could explain the inconsistent association between OCs and insulin. Future analyses could focus on the influence of OCs in groups of women at high risk for glucose intolerance, such as those with endocrinopathies.

While growth hormone plays an important role in hypoglycaemia counter-regulation, it has been shown that oral contraceptives increase growth hormone concentrations. In this context, we tested if serum growth hormone concentrations display a differential response on glycaemic variations in healthy women using oral contraceptives and those not using contraceptives.

Methods: Fifteen healthy women with oral contraceptive treatment and 10 without participated in a stepwise hyper- and hypoglycaemic glucose clamp procedure.

Serum growth hormone concentrations were measured at euglycaemic baseline and subsequently at plasma glucose plateaus of 8. Conclusion: Healthy women on oral contraceptive treatment display an increased responsiveness of growth hormone to hypoglycaemic, as well as hyperglycaemic conditions and generally higher serum growth hormone concentrations than women without oral contraceptives.

Delta values were calculated as post-treatment level minus pre-treatment level of each analyzed variable. All statistics were performed using SPSS Patients randomized to the three treatment groups were comparable regarding all clinical and biochemical characteristics Table 1.

Patients with RH after study intervention were characterized by higher 2-h AUC insulin GLP-1 levels were higher in lean vs obese patients Fig.

Patients with RH had significantly higher fasting GLP-1 8. GLP-1 levels during 5-h OGTT were comparable in patients with RH vs patients without RH. As recently presented, the presence of RH was independent of BMI 9 , data not shown. Women with PCOS had significantly higher levels of insulin fasting, 2- and 5-h AUC and C-peptide fasting, 2- and 5-h AUC vs controls Table 3.

Obese patients with PCOS had significantly higher levels of insulin fasting, 2- and 5-h AUC , C-peptide fasting, 2- and 5-h AUC and HOMA-IR compared to lean patients Table 4. Increased risk of RH after medical intervention was associated with increased insulin levels during 5-h OGTT and was not predicted by AUC GLP-1 or BMI.

Few previous studies evaluated GLP-1 secretion during medical intervention in women with PCOS. Limited data are available on possible interactions between sex hormones and GLP Treatment with GLP-1 increased LH secretion and induced puberty in female rats 17 , Increased LH in PCOS 27 could therefore be associated with higher GLP-1 levels.

We found no association between testosterone and GLP-1 levels and GLP-1 levels were unchanged despite normalized testosterone levels during treatment with OCP, which did not support an association between testosterone and GLP-1 secretion.

In support of this hypothesis, total testosterone levels were unchanged during treatment with GLP-1 despite significant weight loss in patients with PCOS 28 , We found that metformin treatment was associated with unchanged GLP-1 secretion, whereas insulin levels decreased during 5-h OGTT and the median weight loss was 3.

In contrast, Svendsen et al. reported increased GLP-1 secretion during 2-h OGTT after 8-month treatment with metformin in 22 lean and obese women with PCOS 6.

Measures of insulin resistance were unchanged and no reduction in BMI was reported 6. In vitro and in vivo studies in patients with type 2 diabetes and obese non-diabetic subjects, supported that treatment with metformin could increase GLP-1 secretion directly by stimulating the GLP-1 producing cells and by decreasing soluble dipeptidyl peptidase-4 activity and thereby inhibit GLP-1 degradation 30 , We did therefore expect increased GLP-1 levels during metformin treatment.

The median changes in fasting, 2-h and 5-h AUC GLP-1 levels during metformin treatment were positive, but the present long-term study design did not allow the inclusion of a placebo group. It is possible that metformin treatment could have short-term effects on GLP-1 secretion that does not persist during long-term treatment, but more studies are needed to test this hypothesis.

Women with RH after study intervention had higher insulin secretion, whereas glucose stimulated GLP-1 secretion and BMI was comparable in patients with and without RH.

Increased risk of RH was seen in both lean and obese individuals. These findings supported that increased insulin secretion were the primary mediator of increased risk of RH. The power of the present study did not allow us to test the possibility that the mechanism for RH could differ between lean and obese subgroups of patients 9.

The present study did not support our hypothesis that weight gain during treatment with OCP was associated with increased risk of RH However, insulin resistance was deteriorated during treatment with OCP as fasting and glucose-stimulated insulin levels increased.

It is possible that the effects of OCP treatment on insulin and C-peptide levels were too modest to affect the risk of RH. In meta-analyses, treatment with OCP was associated with unchanged fasting insulin in PCOS 16 , but fasting insulin is only a rough measure of insulin resistance 33 and different generation OCPs could have divergent effects on metabolic risk factors Increased ghrelin levels during OCP treatment could be a marker of increased appetite, but previous data on ghrelin secretion during treatment with OCP in patients with PCOS were conflicting 35 , More data are therefore needed on the possible effects of different generation OCPs on metabolic risk including RH, appetite regulation and insulin resistance in PCOS.

We found that GLP-1 secretion was comparable in patients and controls both at fasting and during 5-h OGTT and GLP-1 levels were also comparable in obese and lean subgroups of patients and weight-matched controls.

Results from recent studies on GLP-1 secretion in PCOS were conflicting. The majority of studies found no significant differences in GLP-1 levels between patients with PCOS and weight-matched controls 5 , 6 , 37 , whereas lower GLP-1 levels in lean patients with PCOS vs weight-matched controls were reported in two studies 4 , Our findings are in agreement with the study by Svendsen et al.

in 40 patients with PCOS 6 , reporting comparable GLP-1 levels between patients with PCOS and controls overall and in lean and obese subgroups during 2-h OGTT, whereas less than 25 patients were included in the remaining studies 4 , 5 , 37 , Furthermore, we used up-to-date methods for the measurement of GLP-1 22 in contrast to previous studies 4 , 5 , 37 , Comparable measures of insulin resistance between patients and controls 4 , 5 , 6 , 38 could have affected study outcomes in previous studies.

Our findings of significantly higher measures of insulin resistance in PCOS vs controls further supported that BMI is the most important predictor of GLP-1 secretion in PCOS and that PCOS itself is not associated with changed GLP-1 secretion.

The strength of the present study was the randomized controlled design. A recent publication of similar sample size reported significant changes in GLP-1 secretion during metformin treatment 6.

Furthermore, up-to-date methods were applied for the measurement of GLP-1 This supported that the present study had power to detect changes in GLP-1 secretion during medical treatment. A study limitation was the inclusion of relatively lean women and that the long intervention period did not allow for the inclusion of a placebo group.

Normal-weight patients had high drop-out rates especially in the two treatment arms including metformin, which could lead to type 1 error, thus lack of power. P values were, however, close to one, which support our conclusions.

The pathogenesis of insulin resistance in PCOS is multifactorial and insulin resistance is difficult to assess by mathematical indices Furthermore, there are intra-individual variations in glucose levels, which could lead to misclassification of RH Our findings regarding risk of RH during medical treatment in PCOS therefore need to be reproduced in future studies.

GLP-1 secretion was predicted by BMI and not by PCOS-status. None of the authors have any conflict of interest that could be perceived as prejudicing the impartiality of the research reported. Oral contraceptive pills and metformin tablets were sponsored by Sandoz.

Pancreatic islet cells, important in regulating insulin secretion and glucose metabolism, contain estrogen receptors. It is hypothesized that when estradiol a form of estrogen interacts with those receptors it can help with the survival and stability of islet cells and in stimulating insulin synthesis, which aids glucose metabolism.

Research has established a clear link to early loss of hormones early or premature menopause-ovaries removed early and accelerated aging and development of chronic diseases, including increased risk for heart disease, osteoporosis , dementia and even early death, says Faubion, who coauthored research on the potential long-term health consequences of early menopause.

A study published in Diabetologia in October found that women who had natural menopause at an earlier age age 44 or younger were at a higher risk for developing type 2 diabetes. RELATED: 10 Ways to Beat Menopausal Belly Fat.

The study also found that the use of birth control pills at least once was associated with a 33 percent increased risk of developing type 2 diabetes compared with women who had never used them.

RELATED: The Best and Worst Birth Control Options. Tatulashvili agrees there is no clear explanation why contraceptive pill use is associated with higher risk of type 2 diabetes. Another hypothesis is that birth control pills can lead to higher than normal estradiol levels, which could cause insulin resistance in the liver or a reduction in the efficiency of glucose use and transport in muscle cells, says Tatulashvili.
