Decreased Menstrual Flow: Causes and Concerns - Obstetrics and Gynecology

Decreased menstrual flow, also known as hypomenorrhea, can be a concerning symptom for many women. There are various potential causes for this condition, and understanding them is crucial for addressing any underlying issues.
Firstly, hormonal imbalances are one of the most common reasons for changes in menstrual flow. The menstrual cycle is regulated by a complex interplay of hormones, including estrogen and progesterone. If there is a disruption in the production or balance of these hormones, it can lead to lighter periods. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or even stress can significantly impact hormone levels.

Another important factor to consider is lifestyle changes. Weight fluctuations, whether it be significant weight loss or gain, can affect menstrual flow. For instance, excessive exercise or restrictive diets can lead to decreased body fat, which in turn can lower estrogen levels and result in lighter periods. Similarly, stress and anxiety can also play a role in menstrual irregularities, as they can affect the hypothalamus, the part of the brain that regulates the menstrual cycle.

In addition to hormonal and lifestyle factors, certain medical conditions can also lead to decreased menstrual flow. For example, uterine fibroids or polyps can alter the normal menstrual pattern. Endometriosis, a condition where tissue similar to the lining inside the uterus grows outside of it, can also cause changes in menstrual flow and may be associated with pelvic pain. Given that you mentioned experiencing intermittent pain on the left side of your uterus, it would be prudent to consider this possibility.

Furthermore, contraceptive methods can also influence menstrual flow. If you are using hormonal birth control, it may lead to lighter periods or even missed periods altogether. This is particularly common with certain types of hormonal IUDs or birth control pills that contain lower doses of hormones.

Regarding your concern about whether your sexual activity may be related to the changes in your menstrual flow, it is generally unlikely that sexual intercourse would directly cause a decrease in menstrual flow. However, if there are underlying issues such as infections or pelvic inflammatory disease (PID) that could be related to sexual activity, these could potentially affect your menstrual cycle.

Given the complexity of menstrual health, it is essential to consult with a healthcare provider to discuss your symptoms in detail. They may recommend a physical examination, blood tests to check hormone levels, or imaging studies such as an ultrasound to evaluate the uterus and ovaries for any abnormalities.
In summary, decreased menstrual flow can result from a variety of factors, including hormonal imbalances, lifestyle changes, medical conditions, and contraceptive use. The intermittent pain you are experiencing could be related to several conditions, and it is advisable to seek medical attention to rule out any serious issues. Keeping track of your menstrual cycle, any associated symptoms, and discussing these with your healthcare provider will help in determining the best course of action for your health.
