Discover why your abdomen swells at the end of the day and how to take care of it

Experts explain the factors behind bloating and how to maintain digestive health

Waking up with a flat abdomen and ending the day feeling bloated is more than an aesthetic issue; It reflects what happens inside the organism. The sensation of swelling can be punctual or chronic, but it always deserves attention if it is repeated frequently.

Dr. Malena García Arredondo, digestive system specialist and director of MGA Healthy Digest at the Memorial Publio Cordón Hospital in Pozuelo de Alarcón, warns that “it is not just about what we eat, but about how our digestive system works as a whole.”

One of the phenomena that explains this daily variation is abdominophrenic dyssynergia. In this case, the diaphragm descends and the abdominal wall relaxes, causing the abdomen to bulge without any real increase in volume. This effect generates the visible difference between morning and night.

The specialist points out that loosening your pants at the end of the day can be normal if it is occasional and mild. However, when bloating is intense, frequent or accompanied by pain, changes in intestinal transit or fatigue, it is essential to consult. “The relevant thing is not that it ever happens, but rather its frequency, intensity and how it impacts the quality of life,” García Arredondo clarifies.

A common mistake is to believe that there are foods that are universally prohibited. Digestive tolerance is very individual. Legumes, cruciferous vegetables, dairy products or foods rich in FODMAPs can cause fermentation, but they do not affect everyone equally. The microbiota, intestinal sensitivity, stress and pace of life play a determining role.

Sometimes the feeling that “everything feels wrong” comes not from a specific food, but from a broader digestive imbalance. Therefore, identifying the real cause is key to addressing the problem in an effective and personalized way.

Regarding foods that could help “de-bloat”, there are no miraculous solutions. However, certain ingredients such as ginger, turmeric, yogurt, kefir, oily fish and extra virgin olive oil support the microbiota and help control inflammation. The key is to understand the individual functioning of the organism.

It's not just what we eat that matters, but how we cook it. Simple steamed, boiled or grilled preparations facilitate digestion. On the contrary, fried foods, battered foods or fatty sauces slow down gastric emptying, increasing the feeling of heaviness. Legumes, for example, are more digestive if they are soaked and cooked properly or consumed in cream form.

Abdominal bloating does not depend solely on diet. Stress, constipation, eating speed and digestive sensitivity also influence, forming the gut-brain axis, which connects the digestive system with the nervous system. “Digestion is not only a physical process, but it is deeply linked to the nervous system,” explains the specialist.

Many people confuse bloating with weight gain. Body fat is stable, while abdominal distension fluctuates throughout the day, worsens after meals and improves after having a bowel movement, indicating a digestive and non-metabolic origin.

Beyond specific discomforts, low-grade chronic inflammation is a key concept in modern medicine. This silent state can cause persistent fatigue, recurring digestive problems, intestinal disorders, skin problems or difficulty maintaining weight. The microbiota, the immune system and the nervous system interact in the intestine, regulating much of our health.

García Arredondo is committed to an approach that goes beyond treating symptoms, focusing attention on the root cause and promoting intestinal health as a pillar of global well-being. “When the digestive system works correctly, the body also reflects it,” he concludes.
