Doctor Reveals 5 Hidden Causes of Bloating Not Linked to Diet

Bloating

is among the most common digestive issues, but it is attributed to being foo related. However, according to UK-based Dr Sami Kader, that is not entirely true. Responding to a patient’s concern, he explained that bloating can stem from multiple causes - many of which have nothing to do with what you eat. According to Dr. Kader, a patient of his - a woman who had eliminated dairy, sugar, and gluten from her diet still experienced persistent bloating. This highlights an important fact: digestive discomfort is not always diet-related.Also read: Beat the Heat With Safed Jamun: 93% Water Fruit That Hydrates in Summer

What causes bloating?

Dr. Kader explains that bloating typically occurs due to two main reasons: gas buildup or increased pressure and fluid in the gut. From there, he outlines five key causes:

Constipation

One of the most overlooked causes of bloating is constipation. “That is because if you are not emptying your bowels regularly, pressure will build up,” said Dr. Kader. When bowel movements are irregular, waste builds up in the digestive system, leading to pressure and discomfort. This can make your stomach feel swollen and tight.

Gas from fermentation

Certain foods - especially carbohydrates- are broken down by gut bacteria, producing gases like hydrogen and methane. This process, known as fermentation, can cause bloating. Foods like beans, onions, fizzy drinks, sugar, and alcohol are common triggers. Methane, in particular, can slow digestion and worsen symptoms.

Food intolerances

While bloating isn’t always about diet, food intolerances still play a role. Conditions like lactose intolerance or sensitivity to high-FODMAP foods can make digestion difficult. This leads to gas, discomfort, and abdominal swelling after eating items like bread, milk, pasta, or certain fruits.

Swallowing air

A surprising non-diet cause of bloating is swallowing excess air. This can happen if you eat too quickly, talk while eating, chew gum, use a straw, vape, or drink carbonated beverages. The trapped air builds up in the stomach, causing discomfort.

Hormonal changes

Hormones also play a significant role in digestion. "That includes stress hormones like cortisol, thyroid hormones, estrogen, progesterone - it’s quite a big topic,” said Dr. Kader. Stress hormones like cortisol, as well as estrogen, progesterone, and thyroid hormones, can affect gut function. Hormonal fluctuations may slow digestion, increase sensitivity, and lead to bloating.

Can cancer cause bloating?

In a few rare cases, persistent bloating can also signal serious conditions like Ovarian Cancer. Symptoms to watch for include:

• A constantly swollen abdomen
• Pelvic pain
• Loss of appetite
• Frequent urination
• Unexplained weight loss
• Constipation or diarrhoea
• Back pain
• Feeling extremely tired all the time

Health authorities recommend consulting a doctor if bloating is persistent or does not improve with dietary changes. Warning signs include unexplained weight loss, blood in stools, or severe abdominal pain. Emergency symptoms, such as:

• Vomiting blood
• Difficulty breathing
• Sudden intense pain

Bloating is not always caused by what you eat. Factors like constipation, gas, air swallowing, and hormonal imbalances can all contribute. Understanding these causes can help you manage symptoms more effectively. If bloating persists, seeking medical advice is essential to rule out underlying conditions and ensure proper treatment.
