Mild pain in the left side of the abdomen can be caused by improper diet, enteritis, urinary tract stones, pancreatitis, muscle strain, and other factors.

1. Improper diet: Overeating or consuming excessive spicy or greasy foods may increase the burden on the gastrointestinal tract, leading to indigestion and gastrointestinal dysfunction, which can manifest as mild pain in the left abdomen.

2. Enteritis: Enteritis is usually caused by bacterial infection, food poisoning, or autoimmune factors, leading to congestion, edema, and inflammatory response in the intestinal mucosa.

3. Urinary tract stones: Urinary tract stones may cause pain in the ureter or bladder, with pain radiating to the left side of the abdomen. When stones move or become lodged in the ureter, they can irritate the ureteral wall and cause pain.

4. Pancreatitis: Pancreatitis may be caused by biliary tract disease, excessive alcohol consumption, and other factors, leading to inflammatory injury of the pancreatic cells. Symptoms include mild pain in the left side of the abdomen, possibly accompanied by nausea, vomiting, and mild fever.

5. Muscle strain: Strenuous exercise or sudden postural changes may cause muscle strain on the left side of the abdomen, resulting in mild pain at the strained site. Symptoms include localized tenderness and increased pain during movement.

Maintaining good lifestyle and dietary habits in daily life can help prevent mild pain in the left side of the abdomen.
