What causes a dull pain in the lower left abdomen?

Generally, mild pain in the lower left abdomen may be caused by excessive intestinal gas, constipation, ureteral stones, colitis, diverticulitis, or other reasons. If you experience discomfort, seek medical attention promptly. Detailed explanations are as follows:

1. Excessive Intestinal Gas

Excessive gas in the intestines can increase intestinal pressure, stimulating nerve endings in the intestinal wall, thereby causing pain. It is recommended to adjust dietary habits, chew food slowly, reduce intake of gas-producing foods, and perform appropriate abdominal massage to facilitate gas expulsion.

2. Constipation

Constipation is mainly caused by poor dietary habits, lack of physical activity, and不良 bowel habits. These factors can lead to dry, hard stools that are difficult to expel, increasing the burden on the intestines, irritating the intestinal wall, and potentially causing pain in the lower left abdomen. It is advisable to increase dietary fiber intake, drink more water, and maintain regular bowel habits.

3. Ureteral Stones

The formation of ureteral stones is associated with factors such as climate, water sources, diet, and physical activity. When stones move into the ureter, especially the lower segment near the bladder, they may cause pain in the lower left abdomen and may also be accompanied by symptoms such as urgency to urinate and hematuria (blood in urine). Treatment should follow medical advice and may include medications such as progesterone injection, Urolithiasis-Relieving Pills (Niaoshi Tong Pian), and racemic scopolamine tablets.

4. Colitis

Colitis may be related to unhygienic diets, intestinal infections, or changes in weather. Inflammation of the colonic mucosa may lead to pathological changes such as congestion, edema, or even erosion, which can stimulate nerve endings in the intestinal wall, causing pain in the lower left abdomen. Symptoms such as bloody stools and tenesmus (a feeling of needing to pass stools even when bowels are empty) may also occur. It is recommended to follow medical advice and use medications such as smectite powder (Montmorillonite Powder), Enteritis Soothing Tablets (Changyan Ning Pian), and gentamicin sulfate sustained-release tablets for treatment.

5. Diverticulitis

Diverticulitis is mainly caused by blockage of intestinal diverticula by fecal matter or intestinal contents, bacterial infection, or increased intraluminal pressure, leading to inflammation of the diverticula. Under inflammatory stimulation, the aforementioned symptoms may appear, along with bloating and nausea. Treatment can include medications such as ceftriaxone sodium for injection, phloroglucinol injection, and atropine sulfate injection, under the guidance of a qualified physician.

In daily life, it is important to ensure adequate rest and avoid excessive fatigue to promote physical recovery.
