Liver can regenerate by itself. It means that even if a person donates half a liver, it will grow back to normal size within few months. Liver is very resilinet and can develop new cells, but prolonged alcohol misuse (drinking too much) over many years can reduce its ability to regenerate.

Regeneration Process
a. Liver cells, called hepatocytes, multiply to replace lost tissue.
b. This process can restore liver function over weeks to months.
Limits of Liver Repair
a. Chronic damage, such as from alcohol or hepatitis, can impair regeneration.
b. Severe scarring (cirrhosis) may limit the liver's ability to heal.
Factors Affecting Healing

b. Avoiding toxins and maintaining a healthy lifestyle supports liver health.
When to Seek Medical Attention
If experiencing symptoms like jaundice, fatigue, or abdominal pain, consult a healthcare provider. Early intervention can prevent further damage.

Question

I'm really concerned about my cousin's dad. He's dealing with mild hepatomegaly and a grade 1 fatty liver, plus he's got total lung damage. The doctors have basically said there's not much hope and mentioned we might only have as little as 15 to 30 days. Is there anything we can do or try? Any advice would be really appreciated.
