🩺 Glomerulonephritis – Main Cause

Let’s understand this in a very simple way.

What is Glomerulonephritis?
It is an inflammation of the glomeruli, which are tiny filtering units present in the kidneys.

These glomeruli help in filtering waste from the blood. When they become inflamed, kidney function gets disturbed.

What is the main cause?
The most common cause is a Group A beta-hemolytic streptococcal infection.

✅ Correct Answer: Group A beta-hemolytic Streptococcal infection

How does it happen?
Usually, it occurs after:

• Throat infection (like sore throat)
• Skin infection

The body forms antibodies against the bacteria, but these antibodies can affect the glomeruli, leading to inflammation.

Common signs you may see:

• Swelling (especially face and eyes)
• Dark or cola-colored urine
• Reduced urine output
• High blood pressure

Why other options are not correct?

• Staphylococcal infection → Not the most common cause.
• E. coli infection → Common in UTI, not glomerulonephritis.
• Clostridium infection → Causes other diseases, not this condition.

Simple Exam Trick:
Glomerulonephritis → After throat infection → Streptococcus
