What is the reason for lower abdominal pain before menstruation?

If women experience lower abdominal pain before menstruation, it is likely caused by premenstrual syndrome, which is related to hormone imbalance, mental factors, etc. In addition to the above reasons, lower abdominal pain before menstruation may also be related to chronic colitis, chronic pelvic inflammatory disease, tumors, chronic gastritis and urinary stones.

Many women experience lower abdominal pain a few days before their period, which may also be accompanied by diarrhea, fever, nausea, general fatigue, and other symptoms. Lower abdominal pain before menstruation can affect women's daily lives and should be actively treated. So, what causes lower abdominal pain before menstruation?
1. Premenstrual syndrome <br/>If women experience lower abdominal pain before menstruation, it is likely caused by premenstrual syndrome. Premenstrual syndrome can occur not only during menstruation, but also a few days before menstruation. The occurrence of premenstrual syndrome is related to hormone imbalance and mental factors. In addition to causing symptoms of lower abdominal pain, it can also cause breast pain, general fatigue, irritability, irritability, insomnia and other symptoms. These symptoms can gradually disappear after menstruation.
2. Chronic colitis <br/>Premenstrual lower abdominal pain may also be caused by chronic colitis. The occurrence of chronic colitis is related to factors such as allergies and infections, which can cause abdominal pain, bloating, diarrhea, fever, nausea and other symptoms. If this disease occurs during menstruation, it can easily be mistaken for dysmenorrhea, so you should be vigilant.
3. Chronic pelvic inflammatory disease <br/>Chronic pelvic inflammatory disease can also cause symptoms of lower abdominal pain, which may be accompanied by low fever, fatigue, lumbar pain and other symptoms. The above symptoms will worsen after sexual intercourse or fatigue. In severe cases, it can cause insomnia, mental fatigue and other symptoms.
4. Tumor <br/>Lower abdominal pain may also be related to tumors. In addition to abdominal pain, patients with tumors may also experience lower back pain, and these symptoms not only appear before or during menstruation, but may also persist after menstruation. However, since the tumor is small in the early stage, the pain is not very obvious and is easily ignored by patients.
5. Other diseases <br/>Premenstrual abdominal pain in women is not necessarily caused by dysmenorrhea or gynecological diseases. Diseases in other parts of the body can also cause symptoms of lower abdominal pain. For example, chronic gastritis, allergic purpura, peptic ulcer, urinary system stones, etc. These diseases only happen to occur before or after menstruation, which will cause the phenomenon of premenstrual lower abdominal pain.
