What makes you feel nauseous after eating?

1. Infection:

Many of us have experienced this, and it is a horrible experience! The most prevalent cause is food poisoning, however viral gastroenteritis is also a common cause.

Food poisoning is likely if you experience acute nausea followed by vomiting, especially within a few hours of eating. Food poisoning can be caused by a variety of bacteria and the toxins they release.

The disease is self-limiting, as uncomfortable as it may be, but it is critical that you stay hydrated. Keep an eye on your symptoms and get medical help as soon as possible.

2. Pregnancy:

Although this only affects about half of the population, any sexually active woman of childbearing age should contemplate pregnancy.

If you’re using the pill or another form of contraception, it’s critical to see your primary care physician or gynecologist on a regular basis.

3. Dyspepsia:

Indigestion is referred to as dyspepsia. Dyspepsia can be functional (meaning something isn’t operating correctly,


such as issues with “motility,” or how food passes down the digestive tract), or it might be caused by other digestive ailments (e.g. gallstones or inflammation of the pancreas).

Dyspepsia can be temporary, but other people suffer from it for months or years (chronic dyspepsia), which can lead to a slew of consequences, including a decline in quality of life.

4. Drugs and substances:

The majority of medications can produce nausea and vomiting.

Chemotherapeutic chemicals are at the vanguard of this, but illicit substances and even alcohol can cause nausea—after all, the body merely recognizes them as toxins.

5. Anxiety:

Anxiety can be linked to other psychiatric conditions (e.g. anorexia, bulimia, depression, etc.). While these aren’t directly engaged in food digestion, the digestive system is extremely sensitive to our mental and emotional states.


During stressful situations, the body prioritizes the “fight or flight” reaction above digestion functions.

After all, the body doesn’t know what’s producing the stress—it’ll constantly imagine you’re being chased by a tiger, and a tummy full of food would only add to your weight.

This is not an exhaustive list; nausea can also be caused by a variety of other ailments (e.g., allergic reactions, neurological, and metabolic disorders).
