What causes you to feel uncomfortable after a meal?
Many conditions can make you feel bad in your stomach after a meal or feel sick and unhappy after eating a large and fatty food. A simple food poisoning or even a sign that you are pregnant can be the underlying cause of this illness after eating rich foods. It is best to examine the accompanying signs and symptoms more carefully to determine the cause of your condition. Often, nausea and vomiting will accompany the symptoms of this illness.
If you feel sick following a fatty or bulky meal, you may have this feeling for one of the following reasons:
- Food allergies:
Many foods, especially fatty foods containing eggs or seafood, can irritate some people’s immune systems. And the immune system may release Histamine or other chemicals that can cause allergic symptoms. In addition, they can cause mouth, tongue, and upper respiratory tract swelling, urticaria, and even vomiting.
Milk and milk-derived products like cheese can cause food allergies.
- Toxins in food:
Foods that contain large amounts of fat and are stored incorrectly for a long time can have a variety of viruses, parasites, and bacteria.
Consumption of these foods may cause you various symptoms as follows:
- Lethargy and boredom
Usually, if the cause of your discomfort after a heavy meal or fatty foods is toxins, you will develop symptoms in the first few hours after eating.
Food poisoning may cause many different signs and symptoms in our body, from headaches and feeling sick to unconsciousness and death, depending on the type and the amount of the toxin taken.
- Gastric acid reflux:
If you have eaten fatty and bulky food and then feel bored and lazy, especially if you have heartburn or soreness in the back of your throat or you feel that the taste of the food you have swallowed is stuck in your throat and something is stuck in your throat, then the causative factor may be gastroesophageal reflux disease or GERD.
GERD happens when there is a return of gastric acid to the esophagus. The classic symptom of esophageal reflux is heartburn, which usually worsens after eating fatty and greasy foods or sleeping right after meals.
These people suffer from discomfort and even nausea after eating fatty foods. It is said that fats and greasy foods cause the lower esophageal sphincter, which is located between the esophagus and the stomach, to relax.
As the lower esophageal sphincter relaxes, gastric juice return increases.
Another cause that can make you feel sick, full, lethargic, bored, and sometimes nauseous after eating fatty foods is pregnancy.
Usually, these symptoms start around the second month of pregnancy. It is said that hormonal changes during pregnancy cause these conditions in pregnant women.
An increase in Progesterone hormone during pregnancy relaxes the esophageal sphincter and increases the chance of gastric reflux into the esophagus. This condition is sometimes called Morning sickness.
But it is interesting to know that nausea and discomfort can occur in pregnant women in early pregnancy at any time of the day and during eating. Even the smell and taste of food can cause lethargy, nausea, and boredom.
The gallbladder is a small sac that is part of the structure of the human liver. The gallbladder is the place where bile secretions are stored. Bile is produced by bile cells in the liver.
Bile fluid is needed to digest fats properly.
When fat molecules move from the stomach into the small intestine, the gallbladder starts to contract and secretes bile into the small intestine.
Therefore, these people will suffer from lethargy and boredom, sharp pain in the right side of the abdomen, which shoots in the right shoulder, followed by greasy foods.
- Bile duct stenosis:
You may have bile duct stenosis if you experience changes in your stool or urine color and feel sick after greasy foods.
- Acute or chronic pancreatitis:
The pancreas is a gland responsible for the secretion of various hormones like insulin, aside from its functions in fat digestion.
Many factors may lead to pancreas inflammation or pancreatitis, varying from alcohol consumption and some medications to virus infections.
The most common cause of acute pancreatitis is gallstones, meaning that the gallstones block the outlet of the pancreas and obstruct the duct.
This obstruction in the passage of pancreatic enzymes will lead to inflammation of the pancreas and various symptoms like pain and sickness after greasy and fatty foods.
One with inflammation of the pancreas or acute or chronic pancreatitis has inflammation and damage to the pancreas.
They may also experience nausea, vomiting, and pain in other areas of the abdomen and chest.
- Irritable bowel syndrome:
This syndrome is called IBS for short. One with IBS can have a set of symptoms for unknown reasons. They may develop the following symptoms after eating large or fatty foods:
- Abdominal pain
- Feeling bored
- Constipation which is less common following fatty food.
- Those who undergo chemotherapy:
Those treated with chemotherapy drugs to treat the tumor and cancer can experience some sickness and nausea after eating fat and fatty foods.
Almost always, these problems will resolve when the chemotherapy ceases.
- Stress and anxiety, and motion sickness:
Those with lots of stress and anxiety and those who are very sensitive to movement may experience nausea and condition as they eat a greasy and fatty meal.
- Stomach Flu:
One of the most common terms the general public uses is Stomach Flu. Stomach flu is when a factor causes inflammation in your stomach and digestive system. Infectious Gastritis is the medical term for stomach flu.
In these cases, the following symptoms occur:
And the unpleasant feeling comes to you after eating, especially fatty and bulky foods.
Stomach flu may occur following the transmission of the pathogen from an infected person to you, or it may be transmitted to you following eating or drinking water or food from an infected container.
- Fatty liver:
As the term implies, the accumulation of fats in the liver may cause fatty liver, interfere with normal liver functions of the liver, and causes different kinds of symptoms that may happen or worsen with heavy and greasy meals.
- Gastric ulcer:
Gastric ulcers and erosions caused by infectious and non-infectious agents may cause many problems with fatty and greasy foods.
There are many causes for the development of inflammation in the stomach that can be infectious or non-infectious.
Some medications like Aspirin and Advil can cause gastritis.
- Accumulating waste materials like uric acid may lead to a condition named uremia which will cause sickness and problems while eating fatty and greasy foods and diets high in proteins.
- Chronic renal failure or CRF:
Any kidney function problem may cause uremia and waste materials collection in our body, leading to sickness and problems while eating foods.
