- The stomach
- The spleen
- The pancreas
- The left kidney
- Part of the liver
- Muscles and ribs surrounding the area
Pain in this region may be related to indigestion, gastritis, stomach ulcers, kidney issues, muscle strain, or, in some cases, spleen-related conditions.
The middle left abdomen, often called the flank area, contains portions of the kidney, ureter, intestines, and surrounding muscles. Pain here may result from kidney stones, urinary tract problems, muscle injuries, or intestinal issues.
The lower left abdomen contains parts of the colon, small intestine, and, in women, the left ovary and fallopian tube. Common causes of pain in this area include:
- Gas and bloating
- Constipation
- Diverticular disease
- Intestinal infections
- Ovarian cysts
- Menstrual-related discomfort
- Urinary tract conditions
Many people immediately worry when they feel pain on the left side, but mild pain is often caused by temporary digestive issues. Gas trapped in the intestines, for example, can create surprisingly sharp discomfort that may come and go throughout the day.
Muscle strains are another common culprit. Lifting heavy objects, exercising, coughing excessively, or even sleeping in an awkward position can irritate muscles and cause localized pain that worsens with movement.
However, some symptoms should never be ignored. Medical evaluation may be necessary if left-sided pain is accompanied by:
- Fever
- Persistent vomiting
- Blood in urine or stool
- Severe tenderness
- Difficulty breathing
- Chest pain
- Dizziness or fainting
- Sudden severe abdominal pain
