Reason for stomach ache in giardiasis 

1. The pathogens invade the gut lining and cause inflammation

2. There are muscle cramps due to the inflammatory response 

3. Gas formation leads to stomach ache

4. There is absorptive disorder. Bile salts are not absorbed and there is imbalance of acid formation. Hyperacidity is common and this too causes tummy pain. 

Prompt treatment with oral metronidazole or secnidazole cures the disorder. Five to seven days course with metronidazole or a stat dose of secnidazole is beneficial. 


Stool sampling may be required for diagnosis if symptoms are unusual or mild or mimic other gut conditions.
