How common is abdominal pain in giardiasis?

Giardiasis is an intestinal infection caused by a parasite. It can disrupt digestion and lead to a gassy, bloated abdomen, loose stools, cramps, and a feeling of urgency. Symptoms can vary from person to person and may be intermittent. Having abdominal pain does not by itself show that giardiasis is present; a healthcare professional considers the whole symptom pattern and possible exposure when deciding whether to test.

Keep drinking fluids and note changes in your stools, appetite, and pain. Tell a clinician about recent travel, untreated water, outdoor activities, childcare contact, or illness in people you live with, as these details can guide testing. Do not share towels where possible, wash hands carefully after the toilet, and avoid preparing food for others while you have diarrhoea. Treatment may be prescribed after clinical assessment.

Get urgent help if the pain becomes severe, constant, or sharply localised, or if you have blood in the stool, vomit that looks like blood, fainting, confusion, or signs of significant dehydration. Contact a clinician if diarrhoea and abdominal symptoms continue, interfere with eating or drinking, or recur after seeming to improve. Earlier advice is sensible for pregnancy, very young children, older adults, or reduced immune function.

You could ask whether your exposure history makes a stool test appropriate, how to collect a sample correctly, and whether household members need any precautions. Ask what changes in pain, hydration, or bowel movements should lead you to seek urgent care.
