What causes hiccups?

I am a 26-year-old woman. For some time now, I have been feeling constantly tired and also have an uncomfortable pain in my abdomen. I have lost interest in eating and I have a loss of appetite. What could be behind this situation? Could it be a chronic disease?

I have been feeling constantly tired for some time now and also have an uncomfortable pain in my abdominal area. I have lost interest in eating and have a loss of appetite.

I am a 42-year-old woman. My stomach hurts. Whatever I eat immediately causes gas.

I have a swelling feeling on the left side of my abdomen, 4 fingers below the belly button, and sometimes a pulling pain and gas.

My stomach hurts a lot after eating oily foods, fried foods, raw onions and garlic. Is the problem organ the stomach or the gallbladder?

My stomach hurts and I feel nauseous. Which doctor should I go to?

I would like a real Internal Medicine, Gastroenterology doctor to answer my question.

Until a week ago, when I ate eggs or eggs with potatoes, I had severe pain in my stomach and it wouldn't go away for 1-2 hours. Until a few days ago, the severe pain decreased but it still hurt a little, today I didn't feel any pain even though I ate eggs, what could be the reason?
