The liver is a powerhouse, as it serves the body by doing more than 500 important tasks. Once this vital organ starts accumulating extra fat, over 5 per cent of its weight, then it causes fatty liver disease. Though commonly linked to the elderly, the problem is rising at an alarming rate among young people in the world today. The cause of this change is mostly the modern lifestyles and changes in the metabolic pattern. It is a serious illness which needs to be addressed at a tender age, as the complications that this disorder can trigger are acute and chronic. The first thing that will ensure your long-term health is to learn about the causes and practice preventive steps to ensure that you are safe from fatty liver disease.

What Exactly Causes Fatty Liver Disease in Young Adults?

Fatty liver disease is a broad term that refers to two distinct types of the condition, including Metabolic Dysfunction–Associated-Steatotic Liver Disease (MASLD, previously called NAFLD) and Alcoholic Liver Disease (ALD). The increasing cases of MASLD among the younger generations are greatly associated with diet and activity levels.

The major contributors are:

• Excess Body Weight and Obesity: Excess body fat build-up, especially in the abdominal area, is the greatest cause of MASLD. Statistics indicate that a large number of adults who are diagnosed with this disorder are overweight or obese.
• Type 2 Diabetes and Insulin Resistance: The inability of the body to respond to insulin results in the liver storing the excess energy in fat. MASLD is also present among a high percentage of patients with Type 2 diabetes.
• Dietary Choices: Diets that are dramatically high in processed food, refined carbohydrates (white bread and sweet cereals), saturated fats, and sweetened drinks are all associated with an excessive amount of fat load on the liver.
• Sedentary Lifestyle: Physical inactivity means that the body is not able to efficiently utilise glucose and fats, and thus they lead to metabolic failure directly.
• Abnormal Blood Fats: These abnormal levels of triglycerides or poor levels of the good cholesterol (dyslipidaemia) are closely linked with fat build-up in the liver.
• Excessive Alcohol: Heavy or regular intake of alcohol may cause damage to liver cells, as well as promote ALD or exacerbate MASLD, particularly in patients who are already prone to metabolic dysfunction.

What Are the Risks and Fatty Liver Disease Symptoms?

Fatty liver disease has non-specific or no symptoms in its early stages, which gives it the name of the ‘silent’ disease. A great number of young adults are totally oblivious to the fact that they have the condition before finding out about it in the course of routine blood work or imaging scans. Unattended, the disease may progress to the following deadly stages:

• Steatohepatitis (MASH): In this inflammation stage, fat accumulation in the liver is elevated, which causes inflammation and destruction of liver cells.
• Fibrosis: Persistent inflammation leads to the accumulation of scar tissue in the liver. At this level, the liver functions are impaired.
• Cirrhosis: It is a permanent, widespread scarring that greatly impairs the function of the liver. Cirrhosis is associated with high chances of liver failure and liver cancer.
• Cardiovascular Risk: Patients who have fatty liver disease are at high risk of acquiring heart disease, and, unfortunately, it is the most common cause of death in patients.

Though the signs typical of the severe fatty liver disease, e.g., the yellowish skin colour (jaundice), chronic fatigue, or fluid retention (oedema), are not observable until the disease reaches its most serious phases, it is important to recognise the fact that the damage will be occurring silently at a lot of stages before the signs of the mentioned problems will become evident.

What Are the Proven Fatty Liver Disease Treatments?

• Drugs: Approved drugs for certain types of fatty liver disease include Resmetirom for noncirrhotic nonalcoholic steatohepatitis (NASH or MASH) with moderate fibrosis and semaglutide for moderate to advanced scarring from MASH. Other medications like pioglitazone, pentoxifylline and vitamin E may be beneficial. One must keep it simple since there is no wonder drug or approved drug that can cure fatty liver disease until now. Deep-rooted and sustainable lifestyle changes are the most effective and long-term forms of treatment for fatty liver disease. The bright side is that once it is diagnosed at a young age, the condition is often reversible if a person commits to working hard.
• Weight Loss: This is the treatment keystone. Losing 5-10 per cent of the total body weight, which may lead to a significant reduction of the liver fat and inflammation. To be safe and effective, it must be gradual (with an objective of 1-2 pounds a week).
• Dietary Overhaul: Implement a healthy diet, e.g. Mediterranean diet. The stress should be on the elimination of processed sugars, refined carbohydrates and saturated fats. Eat larger quantities of vegetables, fruits, and whole grains, not to mention healthier fats (nuts and olive oil).
• Regular Physical Exercise: At least 150 to 300 minutes of moderate aerobic exercise should be done weekly. This, supplemented with muscle-strengthening exercises 2-3 times a week, as exercise does improve insulin sensitivity and helps burn body fat, which is key for fatty liver disease self-care.
• Alcohol Abstinence: When cases are diagnosed of having ALD or individuals whose MASLD is severe, then there is no alternative to having the liver heal other than complete abstinence from alcohol.
• Managing Co-existing Conditions: Professionals should work with a healthcare provider to manage co-existing health conditions like high cholesterol, high blood pressure and diabetes. These underlying problems may need medications.

What is the Life Expectancy with Fatty Liver Disease?

The issue regarding life expectancy in the case of fatty liver disease is complicated and is closely tied to the progression of the disease and adherence to lifestyle changes. It is impossible to give any definite dates and make promises.

• Early Stages (Simple Steatosis): When the disorder represents the simple accumulation of fat without inflammation (steatosis), the prognosis is mostly favourable, assuming the patient is ready to make major adjustments in their life. The progression can be controlled, and the condition might be reversed.
• Advanced Stages (Cirrhosis): In the case of the disease turning into cirrhosis, risks are high. Survival rates of patients with advanced and decompensated cirrhosis after five years are, unfortunately, significantly lower. The further development of severe liver disease is strictly connected with the continuation of an unhealthy lifestyle and the appearance of underlying diabetes or severe obesity.

The most significant point is that the illness is not that fast-paced and leaves people with an essential amount of time. Consistent fatty liver disease treatments (through self-care and medical advice) offer the best opportunity to stop and even reverse the damage caused by aggressive fatty liver disease. Delayed action is bound to lead to a reduction in life expectancy with fatty liver disease.

Nanjappa: The Hospital Where Young Adults Seek Expert Help?

When it comes to fatty liver disease symptoms or risk factors, expert medical opinion must be sought immediately, provided that there is a suspicion of either having the condition or putting someone at risk. The good point to start is with general practitioners, but specialists’ care from gastroenterologists and hepatologists is required to diagnose it (with imaging or even elastography) and prepare an effective treatment plan. The identification of a multi-speciality hospital with a high level of diagnostic possibilities is essential to manage this chronic disease and deal with its metabolic complications.

The region must have a reputable centre that handles digestive health and metabolic disorders in people who require thorough care. Such centres provide the full spectrum of care, from high-level dieticians, diagnostics and physiotherapists to advanced diagnostic technology. Such a comprehensive, integrated approach to medicine is the Nanjappa Hospital, one of the best hospitals in Shimoga, providing management of a chronic condition such as fatty liver disease.
