Fatty liver has become one of the most common health problems in our society, and it often goes unnoticed until it is too late. At the beginning it does not warn, it does not hurt or interfere much in daily life, but little by little it wears down the body until it causes extreme fatigue, heavy digestion and, in severe cases, serious complications like cirrhosis or even liver cancer.

Doctor Saurabh Sethi, a gastroenterologist trained at Harvard, has discovered that there are five simple signs that can be monitored from home and that help detect this problem before it advances too much, and we, as always, are going to tell you about them.

What is fatty liver

Basically it is a disease that happens when fat accumulates in the liver tissue. It is usually related to obesity, but it is not always linked to excess weight, diets loaded with sugars, refined flours and ultra-processed foods are its main cause.

The problem is that when the liver gets saturated, it stops efficiently doing its role as the body’s filter: it processes fats worse, eliminates fewer toxins and ends up damaging itself little by little.

Five warning signs

  1. A sudden increase in waist size, without changes in diet or exercise routine. It happens because fatty liver alters insulin and causes fat to accumulate in the abdominal area.
  2. Sleeping well and still feeling that the body does not perform is another sign. The liver is an “energy engine” and when it fails, that persistent fatigue appears that does not get better even with rest.
  3. The liver is just under the rib cage on that side. If it becomes inflamed, it can generate dull pain or pressure, especially after eating or exercising.
  4. An overloaded liver does not regulate toxins or hormones well. The result is drier skin, itching, pimples or even a yellowish tone in eyes and skin.
  5. A damaged liver directly affects digestion. Nausea after light meals or unexplained loss of appetite are warnings that should be paid attention to.

Not all fat is bad

Doctor Sethi stresses that the big problem is not just fat, but added sugars, corn syrups and processed oils. On the other hand, healthy fats, like those from avocado, olive oil or nuts, help reduce inflammation and protect liver function.

How to take care of it and prevent problems

You have to eat balanced, exercise regularly, sleep enough and limit alcohol and ultra-processed foods.

Here we leave you a list so that every day you can combine one option from each group and take good care of that liver!
