PCOS, also known as Stein-Leventhal syndrome, occurs when the female body is high in male hormones compared to the female hormones. Cysts in a string pattern form in the Uterus or Ovary and affect the menstrual cycle. PCOS, if left untreated, can also cause infertility or stop the menstrual cycle.


Obesity has many side effects, one of which is irregularities in the menstrual cycle. Extensive weight affects the hormones and body insulin levels resulting in an uncertain period cycle and irregular blood flow.


The thyroid can be of two types: overactive thyroid (hyperthyroidism) or second, Underactive thyroid (hypothyroidism). Thyroid problems either cause extensive weight gain or comprehensive weight loss along with phatic and sensitivity to cold. If you have irregular periods due to thyroid issues, you may experience increased cramping and abdominal pain, and heavy blood flow.


Anemia and malnutrition cause rapid weight loss or extreme weight gain and have a negative effect on the menstrual cycle. Eating disorders interfere with hormones needed for ovulation.


Having an unhealthy lifestyle, eating an unbalanced diet, not exercising or over-stressing yourself with work without enough rest, and changing sleep patterns have also been proven to interfere with the menstrual cycle.


Some medications that interfere with your menstrual cycle and cause irregular periods are antidepressants, hormonal therapy replacement, chemotherapy drugs, epilepsy drugs, blood thinners, etc. If you are on any of these medicines and experience irregular periods, consult your doctor to change medications. Medicines like Aspirin, Non-steroidal anti-inflammatory drugs (NSAIDs), Naproxen, etc. can affect the menstrual cycle


Fibroids are caused when extensive cell growth happens over the uterus wall, and muscular tumors develop. Generally, fibroids are non-cancerous, but some can develop carcinogenic cells in later stages. Fibroids cause leg pains, painful intercourse along painful and heavy periods, and thus also result in anemia.


Along with irregular periods, if you’re bleeding between your periods or having extensively heavy periods, this can be a sign of cancer. Another significant sign is bleeding during or after intercourse or having unusual vaginal discharge.
