As the monsoon season rolls, it also brings with it the undercurrents of health concerns. Waterborne diseases hit an all-time high. The most pressing threats: Hepatitis A and E, which together account for nearly 45% of acute viral hepatitis cases in India, with incidences peaking during the monsoon and post-monsoon months (June to October). 

Preventive healthcare becomes not just important, but essential in such a scenario and simple diagnostics like Liver Function Tests (LFTs) can play a critical role in early detection and protection against serious liver infections.

What Are Liver Function Tests (LFTs)?

LFTs are a set of blood tests that give a snapshot of your liver's health. They measure enzymes, proteins, and substances like ALT, AST, ALP, bilirubin, and albumin, which tell you how well your liver is functioning or if it’s under stress. Think of it like a diagnostic check-up for your car — only this time, it’s your liver we’re trying to keep in top gear.

For example, if you’ve been feeling tired for no clear reason, experiencing mild yellowing of the eyes, or noticing changes in digestion, your liver might be asking for help.

Why Is Monsoon a Red Flag Season for Hepatitis?

Imagine this: it’s raining, and you’re blissfully sitting inside with a hot steaming plate of momos.

Just perfect, right? But what is also perfect are the chances of water contamination, making us more vulnerable to infections like Hepatitis A and E, which spread through the faecal-oral route — often via unsafe water and unhygienic food. 

According to a 2024 study published in the Indian Journal of Medical Microbiology, a significant rise in Hepatitis E cases was recorded during and after the monsoon, largely attributed to contaminated municipal water and poor sanitation.

Umbrella for the Rain, LFT for your Liver

Consider your liver as the unit where all the processing happens. It is like your body’s chemical plant — it processes nutrients, detoxifies your system, produces bile for digestion, and stores essential vitamins. Damage to this vital organ doesn’t always come with dramatic symptoms. Often, mild viral hepatitis may go unnoticed until it causes significant liver stress.

A simple LFT can detect liver inflammation early. For instance, elevated ALT or bilirubin levels can signal infection or liver strain long before symptoms show. Instead of waiting for a fever or jaundice to strike, early testing allows you to course-correct with hydration, rest, and treatment.

Are Liver Function Tests (LFTs) Only For The Sick?

In a country where visiting the doctor is last on the list when illness strikes, preventive testing is often ignored. But just like you'd check your brakes before a road trip, getting an LFT during monsoon is a smart, preventive step — especially if you:

• Love eating street food
• Have young children or elderly family members at home
• Have had  jaundice or hepatitis previously
• Have no explanation for unexplained fatigue & digestive issues
