What causes pain on the left side of the navel?

Pain on the left side of the navel may be caused by excessive exercise, abdominal cold exposure, viral enteritis, kidney stones, intestinal obstruction, or other reasons. 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. Excessive exercise: Intense physical activity or suddenly increasing exercise intensity after a long period of inactivity may lead to abdominal muscle strain, resulting in pain on the left side of the navel. It is advisable to reduce exercise intensity appropriately, perform stretching after exercise to help relax muscles, and allow adequate rest, which typically alleviates symptoms.

2. Abdominal cold exposure: Not covering the abdomen during sleep or consuming excessive cold foods may cause the abdomen to become chilled, leading to intestinal spasms and cramping pain in the left abdomen. Patients are advised to consume warm foods such as millet porridge and red dates, avoid exposing the abdomen to cold, and apply a hot water bottle to the abdomen to help relieve the condition.

3. Viral enteritis: This is often associated with unhygienic eating utensils or insufficiently heated food. Inflammation may disrupt intestinal flora balance, producing harmful gases that irritate the intestinal mucosa, potentially causing pain on the left side of the navel, usually accompanied by symptoms such as diarrhea and fever. Patients should follow medical advice and take medications such as Acyclovir capsules, Oseltamivir phosphate capsules, or Levofloxacin tablets.

4. Kidney stones: These may be related to metabolic abnormalities or insufficient fluid intake. As stones move within the kidney, they may irritate the ureteral wall, causing pain that radiates to the left side of the navel, often accompanied by lower back pain and hematuria (blood in urine). Patients should take medications such as Tamsulosin hydrochloride sustained-release capsules, Potassium sodium citrate granules, or Pishi granules under a doctor’s supervision.

5. Intestinal obstruction: This may result from intestinal adhesions, bowel torsion, or similar factors. Intestinal obstruction typically increases pressure within the intestine, stimulating intestinal contractions and causing severe pain on the left side of the navel, possibly accompanied by reduced stool output or inability to pass stool. Patients should seek prompt medical care and may require surgical treatment such as bowel resection and anastomosis.

In daily life, patients are advised to eat small, frequent meals and consume vitamin-rich fruits such as oranges, grapes, and pomegranates. Maintaining sufficient sleep may also help alleviate the aforementioned symptoms.
