Introduction
Pain in the lower left abdomen after eating may be related to improper diet, irritable bowel syndrome, intestinal spasms, colitis, intestinal obstruction, and other factors. Treatment can be carried out through daily lifestyle adjustments and medication. Consuming excessive spicy, stimulating, raw, or cold foods may irritate the intestinal mucosa and lead to indigestion, causing symptoms such as dull abdominal pain, diarrhea, and bloating.

Left lower abdominal pain after eating may be related to improper diet, irritable bowel syndrome (IBS), intestinal spasms, colitis, intestinal obstruction, and other factors. Treatment can involve daily lifestyle adjustments and medication. Specific analyses are as follows:

1. Improper Diet

Consuming excessive spicy, stimulating, or raw/cold foods may irritate the intestinal mucosa and lead to indigestion, causing symptoms such as dull lower abdominal pain, diarrhea, and bloating. It is recommended to maintain a light diet and eat easily digestible foods.

2. Irritable Bowel Syndrome (IBS)
IBS is a common functional gastrointestinal disorder characterized by abdominal pain, bloating, and changes in bowel habits. Left lower abdominal pain is a frequent symptom and is often associated with eating. Under medical guidance, medications such as alverine citrate capsules or pinaverium bromide tablets may be used for treatment.

3. Intestinal Spasms
Respiratory tract infections or local exposure to cold may trigger paroxysmal strong contractions of the intestinal smooth muscles, leading to intestinal spasms. Typical manifestations include lower abdominal pain, which usually resolves spontaneously. For severe pain, patients may take medications such as belladonna tablets or atropine sulfate tablets under medical supervision to relieve discomfort.

4. Colitis
Long-term overeating or consuming excessively spicy food may trigger an acute episode of colitis. Inflammation affecting the colon in the left lower abdomen can cause localized pain. Under a doctor's guidance, patients may take medications such as sulfasalazine enteric-coated tablets or mesalazine enteric-coated tablets to improve symptoms.

5. Intestinal Obstruction
Intestinal obstruction refers to a blockage in part of the intestine that prevents the normal passage of food and fluids. This condition may cause severe abdominal pain and discomfort. Medical attention is required, and treatments may include surgical procedures such as bowel resection with anastomosis or bypass surgery.

Patients are advised to seek immediate medical care to determine the underlying cause and receive appropriate, targeted treatment under professional guidance.
