Bloated Stomach: 8 Common Reasons and How to Treat Them (Evidence Based)

Abdominal bloating is a common and unpleasant experience that can affect people of all ages. It often manifests as a feeling of fullness, discomfort, or tightness in the abdomen. While bloating may be occasional and mild for some, others experience more severe symptoms, including pain, flatulence, burping, and visible swelling.

Bloating typically occurs when excess gas accumulates in the digestive tract, leading to the feeling of being overly full after meals. While bloating usually resolves itself after a few hours, frequent or persistent episodes can indicate underlying issues. In this article, we'll explore common causes of bloating, practical tips to prevent it, and natural remedies to relieve the discomfort.


Why Bloating Happens

Bloating is caused by the accumulation of excess gas in the digestive system. There are two main reasons why this occurs:

  1. The digestive process itself: As food breaks down in the stomach and intestines, gas is naturally produced. This is a normal part of digestion.

  2. Swallowing air: Certain habits, such as eating too quickly or drinking through a straw, can lead to swallowing air, which contributes to bloating.

For many people, bloating is an occasional inconvenience. However, if bloating is frequent or severe, making a few simple lifestyle changes can significantly reduce discomfort.


Reasons You Are Bloated All the Time

1. Eating Too Much or Too Quickly

Overeating is one of the leading causes of bloating. When you consume large portions of food, your digestive system struggles to break down the food efficiently, causing gas to build up in the stomach.

A helpful approach is to eat smaller portions and take your time while eating. It takes about 20 minutes for the brain to register the feeling of fullness, so eating slowly reduces the likelihood of overeating and bloating. Additionally, chewing your food thoroughly helps with digestion by allowing saliva to break down food, and avoiding gulping air along with your meals can reduce gas buildup.


2. Swallowing Air

Swallowing air is another common cause of bloating. Some habits that contribute to this include:

  • Using a straw

  • Drinking carbonated beverages (e.g., soda, sparkling water)

  • Chewing gum or sucking on hard candies

Eliminating or reducing these habits may help minimize bloating by reducing the amount of air swallowed.


3. Stress and Anxiety

Stress has a direct impact on digestion. When you are stressed or anxious, your body diverts blood away from the digestive system to other areas, which can hinder the digestive process and cause bloating. Additionally, stress can lead to shallow or rapid breathing, which increases the amount of air swallowed.

To alleviate stress-related bloating, consider practicing relaxation techniques like deep breathing, yoga, or meditation. Incorporating calming practices into your daily routine can help your digestive system function more efficiently.


4. Gassy Foods

Certain foods are notorious for causing bloating due to their high gas production. Some of the most common culprits include:

  • Beans and legumes

  • Cruciferous vegetables (broccoli, cauliflower, cabbage)

  • Whole grains (high in fiber)

While these foods offer numerous health benefits, they can cause gas and bloating for some individuals. If you experience bloating after consuming these foods, try eating them in moderation and observe how your body responds.


5. Not Drinking Enough Water

Adequate hydration is essential for proper digestion. When you don't drink enough water, your digestive system becomes less efficient, leading to constipation and bloating. Dehydration can also make it harder for your body to process high-fiber foods properly.

Aim to drink 1.5 to 2 liters of water per day to keep your digestive system functioning optimally. Drinking water before or after meals can also help reduce bloating, especially when eating high-fiber foods.


6. Use of Artificial Sweeteners

Many people use artificial sweeteners like sorbitol, aspartame, or high-fructose corn syrup (HFCS) in an effort to reduce sugar intake. However, these sweeteners can cause bloating in individuals who have difficulty absorbing them.

Fructose, in particular, can lead to bloating, as it is not easily absorbed by the body. For those with fructose intolerance, it can travel to the colon, where bacteria ferment the sugar, producing gases that lead to bloating, flatulence, and even diarrhea.

To reduce bloating, avoid foods and drinks containing high-fructose corn syrup and consider using natural sugar substitutes.


7. Dairy Consumption

Lactose intolerance is a common cause of bloating, as many people are unable to properly digest lactose, the sugar found in milk and dairy products. This can result in symptoms such as abdominal pain, bloating, gas, and diarrhea.

If you suspect that dairy is causing your bloating, try switching to lactose-free milk or plant-based alternatives like almond, oat, or soy milk.


8. Medications and Supplements

Certain medications and supplements can cause bloating as a side effect. Some common culprits include:

  • Aspirin

  • Antacids

  • Diarrhea medications (e.g., Imodium)

  • Narcotic pain relievers

  • Fiber supplements (e.g., Metamucil)

  • Multivitamins and iron pills

If you notice that your bloating worsens after starting a new medication, consult your healthcare provider. They may recommend an alternative or adjust your treatment plan.


Natural Remedies for Bloating

While lifestyle changes are the first line of defense against bloating, there are also natural remedies that can help alleviate discomfort.

Herbal Teas

Herbal teas such as peppermint, ginger, and chamomile can be very effective in soothing the digestive system. These teas can help reduce gas, calm the stomach, and promote better digestion.

Foods to Prevent Bloating

Certain foods can naturally reduce bloating. Ginger, papaya, and pineapple are all known to aid digestion and relieve bloating. For more information, check out my article on the top foods to prevent bloating.

Abdominal Massage

Abdominal massage has been used in various cultures for centuries to relieve bloating and promote digestion. Research suggests that gentle abdominal massage can help move stool through the colon, relieve gas, and reduce bloating.


When to See a Doctor

While bloating is usually not serious, it can sometimes be a sign of an underlying health condition. If you are unable to manage your bloating through lifestyle changes and natural remedies, or if your bloating is accompanied by:

  • Blood in stools

  • Persistent diarrhea or vomiting

  • Unexplained weight loss

  • Increasingly painful heartburn

You should schedule an appointment with your doctor. Keeping a food diary and noting the timing of bloating episodes can help your doctor identify potential triggers and guide your treatment plan.
