What causes Diarrhea after Eating

What causes Diarrhea after Eating – If you receive constant diarrhea after eating, you may be suffering from a few different conditions.

If constant diarrhea was developed abruptly, you could have viral gastroenteritis or food poisoning.

If you mark diarrhea after eating certain foods, you may have an allergy to specific proteins located in various foods. If you mark that you develop diarrhea every time you eat, you may have a more severe illness, such as irritable bowel syndrome or celiac disease.

What causes Diarrhea after Eating


Viral gastroenteritis

One of the main symptoms of viral gastroenteritis sometimes called “stomach flu” is diarrhea. If you have stomach flu, you will not be able to keep any food in your system. According to MedlinePlus, it will develop symptoms that after eating can cause episodes of vomiting and diarrhea such as:

  • Nausea
  • Vomiting
  • Stomach pain
  • Chills
  • Abdominal pain and diarrhea

Gastroenteritis is a viral infection that lasts for one to three days and is highly contagious.

If you have stomach flu, implement a mild and straightforward diet while you still have the symptoms.

Avoid eating huge meals and foods that are high in fat, spicy or highly processed.


Food poisoning

Food poisoning happens while you eat or drink something that is poisoned or contaminated. Within a few hours or even a day, you will begin to feel a sickness in your stomach.

Each time you eat something, you will experience diarrhea.

Diarrhea from food poisoning can last up to two weeks after the initial episode.

Food poisoning is usually caused by an adequate lack of hand washing, handling, food, and eating leftovers. Symptoms may include:

  • Cramps,
  • Fever,
  • Chills,
  • A headache,
  • Vomiting and weakness.


Food Allergies

Food allergies can cause persistent diarrhea after eating. MayoClinic.org states that 90% of all food allergies are caused by seven foods: fish, crustaceans, nuts, soy, eggs, milk and wheat.

Food allergy causes inflammation to occur in your small intestine, which causes nausea, vomiting, diarrhea, stomach pain, and vomiting. Food allergies will cause other symptoms to happen, such as rashes, nasal congestion, and asthma.


Other conditions

Two other standard chronic conditions that can cause consistent diarrhea after eating are irritable bowel syndrome, or IBS, and celiac disease.

With irritable bowel syndrome, the nerves and muscles in the intestine can be ultra sensitive; muscles may contract too much while you eat, causing; or your nerves may react when you stretch your gut, beginning cramps. Celiac disease is a situation where gluten, a protein located in wheat, causes damage to the intestine, resulting in constant diarrhea.
