What are the possible causes of left lower abdominal pain in men?

Generally, left lower abdominal pain in men may be caused by improper diet, excessive fatigue, poor bowel habits, appendicitis, or pancolitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Improper Diet

Frequently consuming spicy or greasy foods or excessive alcohol intake may irritate the gastrointestinal tract, leading to left lower abdominal pain. It is important to maintain a balanced diet, reduce intake of irritating foods, drink adequate water, and promote gastrointestinal health.

2. Excessive Fatigue

Physical or mental overexertion can place the body in a state of stress, impairing digestive system function and causing pain in the left lower abdomen. It is essential to properly balance work and rest and ensure sufficient sleep.

3. Poor Bowel Habits

Holding in stool or straining excessively during defecation increases pressure in the left lower abdomen, resulting in pain. Establishing regular bowel habits and avoiding excessive straining is recommended.

4. Appendicitis

Poor long-term dietary habits, bacterial infections, or colds may trigger appendicitis. Severe appendicitis may lead to peritoneal infection in the left lower abdomen, causing pain, often accompanied by symptoms such as loss of appetite and diarrhea. Treatment may include medications such as ampicillin capsules, ibuprofen tablets, or enteric-coated aspirin tablets, as directed by a physician.

5. Pancolitis

Pancolitis is usually caused by bacterial or viral infections. When inflammation persists in the sigmoid colon and rectum in the left lower abdomen, it can cause severe pain, commonly accompanied by symptoms such as diarrhea, bloody stools, and nausea. Medications such as mesalamine enteric-coated tablets, prednisone acetate tablets, or azathioprine tablets may be used under medical supervision.

Maintaining good personal hygiene and a healthy lifestyle—including a balanced diet, moderate exercise, and avoiding smoking and excessive alcohol consumption—is also important in daily life.
