Are you tired of enjoying your meal only to pay the price afterward?
The most common cause of stomach pain and bloating is excess intestinal gas. If you experience a bloated stomach after eating, it may be a sign of a digestive issue.
Bloating can be caused by something as simple as eating too much, too fast. It could also be caused by a food intolerance or other conditions that cause gas and digestive contents to build up. Sometimes, a bloated stomach can be a sign of a more serious medical condition.
What Causes Bloating?
When you begin to feel that pesky tightness and fullness in your stomach, you may wonder what causes it and why it always – or only sometimes – happens. Some possible causes of bloating can include:
Gas
Carbohydrate malabsorption
Difficulty digesting certain carbohydrates (sugars), such as lactose, fructose, and those found in wheat and beans, is a common issue. This could be due to an intolerance or a general difficulty in processing tougher carbohydrates. A nutritionist or GI specialist can help identify specific dietary sensitivities.
Small intestinal bacterial overgrowth (SIBO)
When colon bacteria enter and multiply in the small intestine, it results in an imbalance. This overgrowth can overwhelm the beneficial bacteria that typically maintain equilibrium. While some bacteria are designed to absorb gases produced by others, an excess of certain types and a deficiency of others can disrupt this delicate balance.
Functional digestive disorders
Irritable Bowel Syndrome (IBS) and functional dyspepsia are diagnoses often given when the body experiences unexplained digestive difficulties, with post-meal gas and bloating being common symptoms. It’s important to be aware of more serious symptoms such as diarrhea, constipation, nausea, vomiting, fever, bleeding, anemia, and unintentional weight loss – especially if these symptoms are new to you.
Visceral hypersensitivity
Even with normal gas volume, some individuals experience greater sensations of gassiness and bloating. This phenomenon is often associated with conditions such as IBS and other disorders that affect the gut-to-brain neural pathways. In some cases, a muscular hyperreaction, known as abdominophrenic dyssynergia, can occur. With this condition, abdominal muscles relax and protrude outwards in response to gas, despite a normal gas volume, creating more space in the abdominal cavity.
Digestive Contents
Constipation
Occasional constipation can stem from diet or lifestyle choices, while chronic constipation may indicate an underlying condition. When stool accumulates in the colon, recently digested food remains in the intestines longer than usual, causing everything to expand and leading to bloating.
Bowel obstructions
If you’re experiencing a bowel obstruction, it may not be solely due to backed-up stool. More serious causes can include tumors, scar tissue, strictures, stenosis, or hernias, which can block either your large or small bowels. Additionally, inflammatory conditions such as Crohn’s disease and diverticulosis can damage the small intestines, leading to strictures that narrow the digestive passage.
Motility disorder
Digestive tract disorders can lead to constipation or a general slowdown of digestive processes. These conditions typically affect the muscles and nerves responsible for sensing the contents of the digestive tract.
Examples include:
- Intestinal pseudo-obstruction: Mimics the effects of an obstruction without an actual blockage.
- Gastroparesis: Involves a partial paralysis of the stomach muscles.
- Pelvic floor dysfunction: A condition affecting the muscles of the pelvic floor.
Bloating Treatment and Care
As you can see, there are many possible causes of your bloating. However, there are some ways you can help lower your risk and even prevent bloating, which can include:
- Eating enough fiber
- Drinking enough water
- Exercising
- Practicing mindful eating
- Taking note of sensitivities
These guidelines offer valuable tips to help you alleviate any bloating or digestive disorders you may be experiencing. However, if your symptoms persist for more than a week or continue to worsen, it’s time to consult a gastroenterologist.
