Asymmetrical Abdomen: Fat Distribution or Liver Concerns? - Gastroenterology and Hepatology

The right upper abdomen is larger than the left upper abdomen?


Hello, Doctor.
I am currently overweight, weighing 100 kg.
A few years ago, I noticed that the appearance of my abdomen, specifically the upper right quadrant (below the chest), is more protruded than the upper left quadrant, and it feels soft to the touch.
Last August, I underwent an abdominal ultrasound, and the doctor diagnosed me with moderate fatty liver disease, with no issues related to hepatitis B or C.
My liver enzyme levels had previously exceeded 60 but have since decreased to 23 as I have started losing weight.
I asked the doctor about the protrusion, and he mentioned that it could be due to the rib cage being more prominent in that area or that it could be fat, but there is no similar situation on the left side.
I would like to ask if this could indicate a liver problem, or is it simply an issue of uneven fat distribution?

Hello: If there are any issues with the liver, it is best to consult a clinical physician.
Uneven fat distribution refers to the description of the liver observed in ultrasound and does not cause left-right imbalance.

Understanding asymmetrical abdominal appearance can be a complex issue, especially when there are underlying conditions such as fatty liver disease. Based on your description, it seems that you have been diagnosed with moderate fatty liver and have experienced fluctuations in liver enzyme levels. The asymmetry you are noticing in your abdomen, particularly the right upper quadrant being more prominent than the left, could be attributed to several factors.

Firstly, it is essential to understand that fatty liver disease, or hepatic steatosis, is characterized by the accumulation of fat in liver cells. This condition can lead to inflammation and, in more severe cases, fibrosis or cirrhosis. The fact that your liver enzymes have decreased from 60 to 23 indicates that your liver function is improving, likely due to your weight loss efforts. However, fatty liver can still contribute to changes in abdominal appearance, particularly if there is significant fat accumulation.

The asymmetry you are observing could indeed be related to fat distribution. In individuals with obesity, fat can accumulate in different areas of the body, leading to an uneven appearance. The right upper quadrant of your abdomen may have more subcutaneous fat, which could explain the "soft" feeling you describe. Additionally, the presence of rib bones in that area may create a visual and tactile difference compared to the left side, which could also contribute to the perception of asymmetry.

Another consideration is the potential for organ enlargement or other structural changes. While your doctor has indicated that there are no significant liver issues beyond the fatty liver diagnosis, it is still wise to monitor liver health through regular check-ups and imaging studies. If the liver were to become enlarged (hepatomegaly) due to fatty infiltration, it could potentially contribute to the asymmetrical appearance of your abdomen.

In terms of addressing your concerns, it is crucial to maintain a healthy lifestyle that includes a balanced diet and regular exercise. This approach not only helps in managing fatty liver but also aids in reducing overall body fat, which may help in achieving a more symmetrical abdominal appearance. If you continue to have concerns about the asymmetry or if you notice any changes in your abdominal area, it would be prudent to follow up with your healthcare provider. They may recommend further imaging studies, such as a repeat ultrasound or even a CT scan, to rule out any other underlying issues.

In summary, the asymmetrical appearance of your abdomen is likely due to a combination of factors, including fat distribution and possibly the effects of fatty liver disease. While it is essential to remain vigilant about liver health, the changes you are observing may not necessarily indicate a significant problem. Regular monitoring and a commitment to a healthy lifestyle are key to managing your condition and improving your overall well-being. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice and guidance.
