Savita is 35 years female with gravida-2 and parity-1 is suffering from hepatic encephalopathy. Likely cause will be:
**Core Concept**
Hepatic encephalopathy is a complex neuropsychiatric disorder caused by liver dysfunction, leading to the accumulation of toxins in the blood that affect brain function. The liver plays a crucial role in detoxifying ammonia, a key toxin responsible for hepatic encephalopathy. The condition can be precipitated by various factors, including infections, gastrointestinal bleeding, and medications.
**Why the Correct Answer is Right**
The likely cause of hepatic encephalopathy in Savita is gastrointestinal bleeding. This is because bleeding in the gastrointestinal tract leads to the translocation of ammonia from the gut to the bloodstream, which can then cause encephalopathy. The liver is responsible for detoxifying ammonia through the urea cycle, but in the presence of liver dysfunction, ammonia levels can rise, leading to symptoms of encephalopathy. The increased ammonia levels can also lead to cerebral edema, seizures, and coma.
**Why Each Wrong Option is Incorrect**
**Option A:** Although infections can precipitate hepatic encephalopathy, they are not the most direct cause in this scenario.
**Option B:** While medications can contribute to hepatic encephalopathy, they are not the primary cause in this case.
**Option C:** Dehydration is not a direct cause of hepatic encephalopathy, although it can exacerbate symptoms.
**Clinical Pearl / High-Yield Fact**
In patients with liver disease, gastrointestinal bleeding is a common precipitant of hepatic encephalopathy, and early identification and management of bleeding are crucial to prevent progression of the condition.
**Correct Answer: A. Gastrointestinal bleeding**
