Fainting
In most cases, fainting, also known as passing out, is brought on by a reduction in blood pressure, which limits the amount of blood flow and oxygen reaching the brain.
Some liver illnesses associated with hepatomegaly such as cirrhosis, hepatitis, and congestive heart failure can also cause hypoglycemia. Hypoglycemia, often known as low blood sugar, is when the glucose level drops below 70 mg/dL (3.9 mmol/L) or even below 54 mg/dL (3 mmol/L) in severe cases.
Moreover, chronic liver diseases may dysregulate blood sugar stability, resulting in hypoglycemia. If the blood sugar is low, the brain will save as much energy as it can, which can cause feelings of lightheadedness, nausea, and risk of fainting.
On the other hand, any alteration of the liver’s metabolic, structural, and cellular functions might impair its capacity to maintain the balance between insulin and glucagon. When such disruption affects hepatic glucose output, hypoglycemia may eventuate.
Fainting in hepatomegaly is often associated with a swollen abdomen or vomiting blood. If severe symptoms are present such as problems with memory, confusion, agitation, change in the level of consciousness, change in mental status, extreme fatigue, fainting, and fever, seek immediate medical care.
