Organs that cause pain on the left side



The stomach is a hollow organ that lies between the end of the esophagus and the first part of the small intestine called the duodenum. 
It is subject to various diseases, often associated with the corrosive gastric acid it produces and contains. 
Among the diseases of the stomach that cause pain in the left side of the abdomen are:

The spleen is the largest lymph node in the body, serves to filter blood and remove cellular debris and foreign microorganisms.

Splenic diseases that can cause abdominal pain on the left side are:

  • Splenic infarction,
  • Spleen rupture, often in traffic accidents,
  • Spleen enlargement (splenomegaly).

The diaphragm is the most important muscle for breathing and separates the thoracic cavity from the abdominal cavity. 
During the inspiration pushes the abdominal contents down and the chest cavity expands. 
On the left side, the most important feature is the diaphragmatic opening, allowing the esophagus to connect with the stomach. 
Among the diseases of the diaphragm is abscess, that is, an accumulation of pus under the muscle. 
The diaphragm may be contracted or withdrawn and may cause tension in the abdominal organs such as the stomach and liver. 
In this case it can cause difficulty in digestion and annoyance.

Abdominal pain on the left side when we run or walk fast

The onset of a strong, debilitating pain that lies on the left side of the abdomen just below the rib cage is common among runners.

This pain is common among runners, but scientific research must still find the cause. 
According to the results of a study by DP Morton, the most reliable theories are “diaphragmatic ischemia” and “stress on the visceral ligaments”. 
In other words, the most likely cause is that running decreases the blood supply to the diaphragm, the muscle that is located between the lungs and the stomach. Torsion of the torso can also cause repetitive stress to the smooth muscles of the internal organs.

The pain on the left side while running can be so intense as to give up. 
However, some experienced runners say that exerting direct pressure on the affected area can relieve the symptoms without the need to stop themselves completely. 
Slowing momentarily, keeping your hands firmly on the affected area, the pain may change immediately and thus resume the run.


Treatment for pain in the left abdomen

Since the causes of pain in the left abdomen can be severe, a visit to the doctor or the local emergency room should be the first step to take. 
The doctor should feel the area and check the pain level. 
If it is acute, he or she may ask for an instrumental examination of the stomach and intestines to see if there is a tumor or a block. 
If the diagnosis is diverticulitis, the doctor prescribes a liquid diet and antibiotics , This includes several days in the hospital under observation. 
Ulcers usually heal with medication or a change in diet, but some cases are severe and need surgery. 
When a cyst or tumor is found in the ovaries or fallopian tubes, a biopsy is usually done to see if it is carcinogenic.
In some cases, your doctor will perform a hysterectomy  if there is a deadly tumor.
