Left Side Stomach Pain Symptoms, Causes and Treatment

Left side stomach pain is mostly caused by gas, but sometimes it can also be the result of more serious conditions such as diverticulitis, appendicitis, or stomach ulcers, which need immediate medical attention. There are many other symptoms that would help to differentiate between normal gas pain and something serious where you should seek emergency care.

Indigestion is typically characterized by pain in the lower left abdomen, which is accompanied by symptoms such as belching, bloating, or a hard abdomen. If you have upper or lower left side pain, a high fever, nausea, vomiting, or severe stomach pain, seek emergency care to rule out any of the serious conditions listed above.

Other causes of left-side stomach pain

If not due to gas, here are some causes of left side stomach pain -


While appendicitis pain is usually felt on the right side of the body, the initial pain often begins near the belly button and can be misinterpreted as coming from the left. If left untreated, an appendicitis infection can lead to serious complications. Keep an eye out for pain moving to the right side of the abdomen, as well as fever, nausea, and vomiting, and seek medical attention right away.


It is an inflammation of the diverticula pouches in the large intestine and is one of the most common causes of pain on the left side. It leads to abdominal pain, fever, and nausea. It is not a severe condition it can be treated.

Stones in the kidneys

Kidney stones, also known as nephrolithiasis, are calcium or uric acid deposits that accumulate in the kidneys. When they pass through the urinary tract, they are excruciatingly painful. Common kidney stone symptoms include left side or back pain, painful urination, fever, nausea, and vomiting. If you notice any of these symptoms of kidney stone pain, go to the nearest emergency room.


Constipation is another cause of abdominal pain on the left side of the body. Constipation is usually caused by a lack of exercise, dehydration, or a low-fiber diet. Most cases of constipation do not necessitate a trip to the emergency room and can be easily alleviated by increasing daily movement and drinking plenty of water.

Ulcers in the stomach

Stomach ulcers, also known as gastritis or stomach inflammation, are sores in the stomach lining that are frequently caused by infections or the overuse of nonsteroidal anti-inflammatory drugs (NSAIDs). They can cause upper left side pain and symptoms such as nausea, vomiting, and bloody or black stools or vomit. Stomach ulcers can heal on their own, but they frequently recur if not treated properly.
