Kidney and fatty liver issues?


Hello Doctor, yesterday I had an abdominal ultrasound (conducted by Dr.
Wang Wenming at Kaohsiung Medical University).
Dr.
Wang mentioned that there are two small cysts on my left kidney, and he said that they are essentially benign and congenital, so there is no need to worry.
I would like to ask for your opinion on this.
(Three years ago, I had my kidney function checked at Kaohsiung Medical University, and it was normal.
My blood tests in August also showed normal kidney function.)
Additionally, I have a more serious issue with fatty liver: my blood tests showed abnormal liver enzymes with GOT=30 and GPT=52 (the standard is below 40).
My previous blood tests were normal, and this time they were abnormal.
The doctor arranged for me to have an ultrasound, which indicated that I have moderate to severe fatty liver.

1.
I would like to ask if my abnormal liver enzymes could be affected by fatty liver? Could I have fatty liver disease now? I am worried that this indicates inflammation, fibrosis, or cirrhosis of the liver.
Is a slight increase in these enzyme levels very serious? Am I at risk of dying soon?
2.
The doctor mentioned that weight loss can reduce fatty liver.
Is the damage to the liver (cell death, fibrosis) reversible? Or can the blood test results improve, but the liver function may not fully recover? Would this have an impact on my body's detoxification processes?
3.
I would like to know how to adjust my diet to reduce fatty liver.
I am currently trying to develop a habit of drinking oatmeal daily and adjusting my diet to reduce calories.
I am not sure if this is helpful.
4.
I have seen two opinions online: (1) Severe fatty liver means there is a lot of fat in the liver, but it does not necessarily mean the liver is severely damaged; it depends on the individual's condition.
(2) Severe fatty liver indicates significant liver damage, approaching cirrhosis.
I would like to know what the correct understanding of severe fatty liver should be.
I am 176 cm tall, weigh 105 kg, and am 21 years old.
I hope to reduce my fatty liver through dietary adjustments and resuming exercise habits.
I am really worried that my life will turn bleak due to fatty liver.
I sincerely ask for your clarification.
Thank you, Doctor.

Hello, the cyst is indeed benign and does not require special treatment.

1.
Fatty liver refers to the accumulation of fat in the liver due to diet, lifestyle habits, or individual predisposition.
As long as you can maintain a low-fat diet, exercise regularly, have a consistent sleep schedule, avoid staying up late, and refrain from alcohol and smoking, most cases of fatty liver can gradually improve, and liver function tests will normalize.
Currently, it has not progressed to liver fibrosis or cirrhosis, and it is not life-threatening.
2.
Weight loss can indeed help reverse fatty liver, as liver cells can regenerate, and liver function can gradually recover.
3.
The main focus should be on reducing fat and caloric intake, especially avoiding fried foods.
It is advisable to monitor the caloric content of foods.
If you are unsure, consulting a registered dietitian is recommended.
Oats can be beneficial to some extent, but the primary focus should still be on reducing fat and caloric intake.
4.
Severe fatty liver indicates significant damage; however, as long as it has not progressed to cirrhosis, recovery is possible.
Therefore, it is still timely for you to start making changes.
Regarding weight loss, the main approach should be through exercise and dietary habit changes.
There are many books available for reference, and you may also consider consulting a weight loss clinic.
Thank you for your inquiry.

It sounds like you have a lot of concerns regarding your recent health findings, particularly related to kidney cysts and fatty liver disease. Let’s break down your questions and provide some clarity on each aspect.

1. Kidney Cysts: The small cysts on your left kidney that were identified during the ultrasound are generally considered benign, especially if they have been stable over time and your kidney function tests are normal. Simple renal cysts are common and often do not require treatment unless they cause symptoms or complications. It’s good to hear that your kidney function has been normal in previous tests, which suggests that these cysts are not currently affecting your kidney health.

2. Fatty Liver Disease: Your elevated liver enzymes (GOT and GPT) indicate that there is some degree of liver inflammation or damage, which can be associated with fatty liver disease. Fatty liver can be caused by various factors, including obesity, poor diet, and metabolic syndrome. It is important to note that while fatty liver itself is a condition characterized by excess fat in the liver, it can progress to non-alcoholic steatohepatitis (NASH), which involves inflammation and can lead to fibrosis (scarring) and potentially cirrhosis if not managed properly.

- Are your liver enzyme abnormalities due to fatty liver? Yes, elevated liver enzymes can be a direct result of fatty liver disease. However, it’s essential to monitor these levels and possibly conduct further tests to rule out other causes of liver dysfunction.

- Is fatty liver reversible? Yes, fatty liver disease is often reversible, especially in its early stages. Weight loss, dietary changes, and increased physical activity can significantly improve liver health and reduce fat accumulation in the liver. The liver has a remarkable ability to regenerate, so with appropriate lifestyle changes, you can improve your liver function and enzyme levels.

3. Dietary Adjustments: To help reduce fatty liver, it’s crucial to adopt a balanced diet. Here are some dietary recommendations:
- Reduce Caloric Intake: Focus on a calorie deficit if you are overweight. This can be achieved through portion control and choosing lower-calorie foods.

- Increase Fiber: Incorporating foods high in fiber, such as oats, fruits, vegetables, and whole grains, can help improve liver health.

- Limit Sugars and Fats: Avoid sugary drinks, processed foods, and saturated fats. Instead, opt for healthy fats found in fish, nuts, and olive oil.

- Stay Hydrated: Drinking plenty of water is essential for overall health and can help your liver function better.

4. Understanding Severe Fatty Liver: The distinction between severe fatty liver and its potential for damage is nuanced. While severe fatty liver indicates a significant amount of fat in the liver, it does not automatically mean that there is irreversible damage. The liver can still recover if the underlying causes are addressed. Regular monitoring and lifestyle changes are key to managing this condition.

In summary, while your concerns are valid, there is a pathway to improvement through lifestyle changes. Focus on a balanced diet, regular exercise, and maintaining a healthy weight. Consulting with a healthcare provider or a nutritionist can provide personalized guidance tailored to your specific needs. Remember, early intervention and proactive management can lead to significant improvements in your health and well-being.
