Are you Facing Problems With Menstruation?

Menstruation or periods is a normal discharge of blood, tissue and uterus lining that is expelled through the vagina, normally once every 28 days. This process can be associated with several disorders that can affect your normal menstrual cycle. 

These problems include painful cramps during menstruation (dysmenorrhoea), abnormally heavy bleeding (menorrhagia),  a period that lasts longer than seven days, irregular periods, not having any bleeding and the absence of periods in certain instances (amenorrhea).

There are many factors that can cause menstrual problems. They can be caused by hormonal imbalance, stress, usage of birth control pills, uterine fibroids, endometriosis, pelvic inflammatory disease or polycystic ovary syndrome (PCOS)

Coming to PCOS, it is a hormonal disorder in which your ovaries produce more than the normal amount of male hormones called androgens, which are usually present in a smaller amount in females. 

This excess amount of androgen can prevent the release of eggs (ovulation), which causes an irregular menstrual cycle, and heavy menstrual bleeding. Irregular ovulation can also cause numerous small, fluid-filled sacs to develop on the ovaries that can cause sharp pain.

These menstrual problems can be treated with medications and lifestyle changes such as a balanced diet and exercise. There is a lot of research that is ongoing in relation to food and menstrual health. One such food being studied is fennel, which has long been used in folk medicine to treat menstrual issues.  

In traditional medicine, fennel has been thought to regulate hormones, enhance brain function, and improve digestion and eyesight, but is there any concrete scientific proof for the same? Let’s dig deeper.

Fennel Seeds: Benefits for Periods and PCOS

There are studies that point to the anti-inflammatory and appetite-suppressing properties of fennel seeds, which may help relieve symptoms of PCOS. However, more research is needed to solidify these claims.

Anti-inflammatory Nature: PCOS causes a chronic state of low-grade inflammation in your body, which can lead to insulin resistance and high levels of blood sugar. This contributes to an increased risk for Type 2 Diabetes in women with PCOS. 

The antioxidants in fennel, such as vitamin C and quercetin can help reduce inflammation, thus lowering insulin resistance and your chances of developing diabetes.

Weight Loss Aid: Fennel contains anethole, which may help suppress your appetite. This can prevent you from overeating and thus limit your calorie intake. This can contribute to weight loss, which improves insulin sensitivity and helps reduce the symptoms of PCOS. 

Studies suggest that losing around 10% of your weight can help you bring your periods back to normal. This is how fennel seeds may contribute to regulating your periods.

Herbs and spices such as fennel seeds may be used as an adjunct along with PCOS treatment but should not be considered a remedy.

Several studies also suggest that fennel seeds can be used to ease pain caused due to menstrual cramps. However, the effectiveness of fennel seeds in regulating hormones, menstrual cycles, or PCOS is still under investigation and needs more research.
