Woman standing on scale. Bariatric surgery helps hormonal imbalances and with menstrual cycle. Mexico Bariatric Center.Morbid obesity can have a direct relation to hormonal abnormalities and unusual menstrual cycles. In many patients, weight gain can cause hormones to be completely imbalanced and menstrual cycles to be off.

A study occurring at St. Luke’s-Roosevelt Hospital Center in New York monitored 126 women ranging in ages 18 to 49. These individuals underwent bariatric surgery to help reduce their excess body weight. None of the women in the study were of pre-menopausal age, and none of them were in or near menopause about other symptoms. The research shows that weight-loss surgery helps to balance hormones, restores their menstruation, reduces unwanted hair growth, and cures skin problems.

What is Menstrual Disorder?

When the woman’s body hormones are imbalanced, it causes irregular periods. The top 4 common menstrual disorders include,

  • Heavy Menstrual Bleeding
  • No Menstrual Bleeding
  • Painful Menstruation
  • Premenstrual Syndrome (PMS)

Polycystic Ovary SyndromeAnovulation or lack of ovulation occurs when the ovaries do not grow or release an oocyte (egg) during the menstrual bleeding.  Chronic anovulation causes changes in menstrual periods and infertility. The main reason for anovulation is hormonal called Polycystic Ovary Syndrome (PCOS). Hypothyroidism (underactive thyroid) can also affect anovulation cycles and fertility.

Anovulation in obese patients primarily shows up with infrequent or missed menstrual patterns. The menstrual period dysfunctions may completely resolve after weight loss surgery.

The ovulation frequency and female reproductive function improve after Roux-en-Y gastric bypass as well as gastric sleeve surgery.

Weight Loss Surgery Helps Anovulation

The researchers took note of the body mass index (BMI) for all women because of the connection with higher BMI and male hormone prominence, causing menstrual cycle disruption. On average, the BMI for women was 46 and considered to be very high. Before the surgery, 52 percent of the women in the study had periods that were regular, and 39 had periods that were irregular. Also, 22 percent of the women surveyed had no period at all. It is not made clear whether those patients had ever had a period or whether their time had simply stopped at some point or some weight level.

Once the patients had surgery the BMI on average was at 33 for most patients. A total of 99 percent of the women who successfully underwent surgery reported having regular menstrual cycles again. Also, the patients that reported having no periods before the surgery, updated reports of having regular menstrual cycles again after the completed operation. This clearly shows that the surgery and subsequent weight loss associated with it played a significant role in the patients’ return to a regular menstrual cycle of standard length and heaviness.

In addition to the significant weight loss and return to a normal menstrual cycle, many patients found that they had balanced hormones as well. Since weight gain of a serious nature can produce more male hormones in a female body, the reduction in weight returns the body back to its original hormonal state. This means that with the weight loss came with,

  • Reduced excessive hair growth where it was not warranted in a woman; it returned hair growth to normal
  • Reduced hair loss
  • Reduced acne in the patients
  • Reduced a skin condition called acanthosis nigricans, which darkens the skin

Looking to Get Your Hormones In Check?

There are clear indications that there is a direct connection between weight loss due to bariatric surgery and return to normal hormonal levels for patients. A typical menstrual cycle is apparently connected to the weight loss from the surgery as well as a regulation of male hormones in women participating in the operation. Regular menstruation was found as soon as the pressure was reduced allowing women to experience normal female reproduction and control over their body. This also translates into being able to manage emotions on a better level with all cycles being more predictable, regular in length, and consistent with bleeding that is established through the menstrual cycle.
