Causes of stomachache and missed menstruation

Delayed menstruation accompanied by abdominal pain may be caused by pregnancy, endocrine disorders, polycystic ovary syndrome, intrauterine adhesions, thyroid dysfunction, etc. The judgment needs to be based on specific symptoms and examination results.

1. Pregnancy

When women of childbearing age experience menopause and lower abdominal pain, they need to give priority to ruling out the possibility of pregnancy. Implantation of the fertilized egg may cause mild abdominal pain, along with breast swelling, nausea and other early pregnancy reactions. It is recommended to use early pregnancy test strips or seek medical advice for a blood HCG test. If abdominal pain persists after pregnancy is confirmed, you need to be alert to the risk of ectopic pregnancy.

2. Endocrine disorders

Long-term stress, excessive dieting, or staying up late may lead to hypothalamic-pituitary-ovarian axis dysfunction, manifested as prolonged menstrual cycles and premenstrual lower abdominal distention. It can be evaluated through six sex hormone tests. It is necessary to maintain a regular daily routine and supplement with appropriate amounts of vitamin E soft capsules, progesterone capsules and other drugs to regulate the cycle.

3. Polycystic ovary syndrome

The disease is often accompanied by symptoms of oligomenorrhea, acne and hirsutism, and ultrasound shows polycystic ovarian changes. Hyperandrogenemia leads to impaired follicular development and may cause persistent lower abdominal pain. Treatment requires the use of ethinyl estradiol cyproterone tablets, letrozole tablets and other drugs as directed by the doctor, together with metformin sustained-release tablets to improve insulin resistance.

4. Uterine adhesions

Patients with a history of induced abortion or uterine surgery may experience periodic abdominal pain but no menstrual cramps, and hysteroscopy may reveal the formation of adhesions. For mild adhesions, estradiol gel can be used to promote endometrial repair. For moderate to severe adhesions, hysteroscopic adhesion separation is required, and an intrauterine ring is placed after surgery to prevent re-adhesion.

5. Abnormal thyroid function

Abnormal thyroid hormone levels can interfere with the menstrual cycle. Patients with hypothyroidism often experience delayed menstruation and cold and painful lower abdomen, while hyperthyroidism may cause reduced menstrual flow. Five items of thyroid function need to be checked. Hypothyroidism can be taken orally with levothyroxine sodium tablets, and hyperthyroidism can be controlled with methimazole tablets.

It is recommended to record menstrual cycle changes and avoid excessive dieting and mood swings. If you have persistent abdominal pain or amenorrhea for more than 3 months, you need to see a gynecologist promptly and complete ultrasound and hormone testing. You can drink ginger and jujube tea on a daily basis to relieve abdominal pain due to uterine cold, but it is not advisable to take blood-activating drugs by yourself. People who are underweight need to ensure their daily intake of high-quality protein, such as eggs, fish, etc.
