Introduction

In general, a rise in body temperature immediately after menstruation may be caused by hormonal fluctuations, intense physical activity, upper respiratory tract infection, pelvic inflammatory disease, endometritis, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition through general measures, medication, or other treatments under a doctor's guidance. A light diet is advisable in daily life, and spicy or irritating foods should be avoided.

Generally, a rise in body temperature immediately after menstruation ends may be caused by hormonal fluctuations, intense physical activity, upper respiratory tract infection, pelvic inflammatory disease, or endometritis. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition under a doctor's guidance through general management, medication, or other treatments. Specific analyses are as follows:

1. Hormonal fluctuations: After menstruation ends, rising estrogen levels can stimulate the body's temperature regulation center, causing a mild increase in basal body temperature, usually not exceeding 37.5°C. No special treatment is required; simply ensure adequate rest, drink plenty of warm water, and maintain regular sleep patterns. Body temperature will gradually return to normal.

2. Intense physical activity: Engaging in high-intensity exercise right after menstruation can accelerate metabolism and increase heat production, leading to a temporary rise in body temperature. Immediately stop strenuous activity, rest on site or take a slow walk, and use a damp towel to wipe the forehead and armpits for cooling. Body temperature will decrease once the body recovers.

3. Upper respiratory tract infection: Immunity is often lower after menstruation, making individuals more susceptible to viral infections. Besides elevated temperature, symptoms such as nasal congestion and sore throat may occur. Follow medical advice to use medications such as compound paracetamol and amantadine tablets, Lianhua Qingwen capsules, or Ganmaoling granules. Also, keep warm and avoid getting chilled again.

4. Pelvic inflammatory disease: Poor hygiene during menstruation may allow pathogens to infect the pelvic cavity, with inflammatory stimulation causing fever, accompanied by lower abdominal pain and increased vaginal discharge. Follow medical advice to use antibiotics such as ceftriaxone sodium injection, metronidazole tablets, or levofloxacin hydrochloride capsules to control infection. Avoid sitz baths during treatment.

5. Endometritis: Bacterial infection causes inflammation of the endometrium, which may worsen after menstruation, resulting in fever and a sensation of heaviness or discomfort in the lower abdomen. Follow medical advice to use medications such as clindamycin phosphate tablets, cefixime dispersible tablets, or azithromycin dry suspension. Maintain good external genital hygiene and change underwear frequently.

In daily life, maintain a light diet, avoid spicy and irritating foods, and consume more fresh fruits and vegetables rich in vitamins. Avoid excessive fatigue immediately after menstruation and gradually resume exercise. Practice scientific self-care to maintain overall health.
