What causes constant nausea after eating or drinking?

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

I understand how distressing persistent nausea can be, especially when it affects even small amounts of food or liquids. Given your history of a past stomach infection and the current symptoms of low energy and poor sleep, there are a few possibilities we should consider: post-infectious gastritis, acid reflux (GERD or gastroesophageal reflux disease), delayed gastric emptying (gastroparesis), or even anxiety-related nausea.

It is also important to rule out more general causes like vitamin deficiencies, hormonal imbalances, or anemia, especially if lab tests were done.

However, I noticed a major concern: your listed weight of 5 lbs (2.27 kg) is likely an error or misentry, as it’s not compatible with life. If your actual weight is very low, malnutrition or eating disorders may also need to be considered as contributing factors.

For now, I strongly recommend

1. Getting a full blood panel, including iron, B12, thyroid, and liver function.

2. A stool test or abdominal ultrasound if nausea persists.

3. Eating small, frequent meals and avoiding spicy, acidic, or greasy foods.

4. Try a gentle anti-nausea medication like dimenhydrinate or ondansetron, but only under a doctor’s advice.

If symptoms continue for more than a week or worsen, please consult a physician in person to ensure no serious underlying condition is missed. You are not alone; this can be treated, and with the right steps, you can feel better soon.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.
