After eating, i always feel and look bloated. what could it be?

+/- Gastroparesis?: Consider gastroparesis=a slow-emptying stomach that is most symptomatic after the stomach fills from meals. Maybe its functional due to brainstem reflexes induced by eating--often exaggerated in irritable bowel syndrome resulting in altered perception of gut distension, "growling", ;modified transit of food. Sometimes, gastric outlet delay may reflect inflammation, scarring, biliary disease, more.

Esophageal reflux: Gastroesophageal reflux with reflux esophagitis can produce burning pain. Other post prandial pain and bloating can be due to gastritis and hiatal hernia. Recurrent gastritis and peptic ulcer disease are commonly caused by H. pylori infection. Severe reflux esophagitis can lead to peripheral neuropathy due to vitamin deficiency, such as vitamin B12 deficiency.
