Urination 4 to 5 times a day is quite normal.
The causes of this sensation of fullness or pressure in the stomach includes :
- Functional dyspepsia (non-ulcer dyspepsia)
This is a syndrome of symptoms that typically start after eating when there is no diagnostic evidence of any other gastrointestinal disease.
Inflammation of the lining of the stomach commonly due to H. pylori infection or use of NSAIDs. It can progress to a peptic ulcer.
Ulceration in the lining of the esophagus, stomach or duodenum usually as a result of chronic gastritis.
Infection of the stomach and duodenum causing nausea, vomiting, diarrhea and a fever.
Protrusion of a portion of the stomach into the chest cavity through the diaphragmatic opening.
- Gastric outlet obstruction
Delayed gastric emptying due to the conditions like pyloric stenosis, gastroparesis, polyps or a tumor.
Functional bowel disorder that may affect gut motility and characterized by non-specific symptoms like a sensation of bloating. Excessive gas may also contribute to stomach bloating.
Post-operative inflammation of the stomach may cause a sensation of fullness. This feeling may be chronic in surgical resection (removal of a part of the stomach in the treatment of conditions like cancer) or bariatric (weight loss) surgery.
You should go to the hospital if the stomach fullness does not resolve spontaneously.
