Introduction
Consuming large amounts of cold or raw food in a short period can irritate the gastrointestinal tract, causing intestinal spasms and resulting in pain in the lower left abdomen. It is recommended to stop consuming irritating foods promptly, drink an appropriate amount of warm water, and apply a hot water bag to the abdomen for warmth, which generally helps alleviate the pain. During nighttime sleep, if the abdomen is not properly covered, especially the lower left abdominal area, exposure to cold may lead to strong contractions of the intestinal smooth muscle.

  Lower left abdominal pain may be caused by improper diet, abdominal cold exposure, strenuous exercise, enteritis, or ureteral stones, and can be improved according to different situations. It is recommended to visit a hospital promptly for treatment under a doctor's guidance.

  1. Improper diet: Consuming large amounts of cold food in a short time can stimulate the gastrointestinal tract, causing intestinal spasms and resulting in lower left abdominal pain. It is recommended to stop consuming irritating foods, drink warm water in moderation, and apply a hot water bag to the abdomen, which can generally relieve the pain.

  2. Abdominal cold exposure: Failure to cover properly during sleep may cause the abdomen, especially the lower left abdomen, to be affected by cold, leading to strong contractions of intestinal smooth muscles and pain. It is recommended to drink more hot water, wear additional clothing, and keep the abdomen warm.

  3. Strenuous exercise: Engaging in vigorous activities immediately after meals, such as running or jumping rope, can reduce blood supply to the gastrointestinal tract and cause intestinal motility disorders, resulting in lower left abdominal pain. The pain usually subsides gradually after resting. It is recommended to wait 1-2 hours after eating before engaging in strenuous exercise, warm up adequately before exercising, and gradually increase the intensity of exercise.

  4. Enteritis: Pathogens such as bacteria, viruses, and parasites infect the intestines, causing inflammation and damage to the intestinal mucosa, leading to lower left abdominal pain, accompanied by symptoms such as diarrhea, nausea, vomiting, and fever. Patients can take medications such as norfloxacin capsules, smectite powder, and Bifidobacterium quadruple viable tablets under a doctor's guidance to alleviate symptoms.

  5. Ureteral stones: Minerals in urine form crystals that accumulate into stones within the ureter. Stone movement irritates the smooth muscle of the ureter, causing spasmodic pain that is intense and colicky in nature, radiating to the lower abdomen and perineum, accompanied by symptoms such as hematuria, frequent urination, and urgency. It is recommended to follow medical advice to use medications such as diclofenac sodium sustained-release tablets, tamsulosin hydrochloride sustained-release capsules, and lithiasis granules to relieve discomfort.
