Hi Mark, I understand your concern. In your case, I see that the chances of having an intestinal worm infestation is more, like round worm, trichuris or ameobiasis infestation. Taking a course of deworming medicines may help you a lot. You can try taking Tablet. Mebendazole for 3 days. It is a prescription drug. Consult your treating doctor regarding the dosage of the drug for you. Low Haemoglobin value may not improve unless these worms are treated. Get a stool routine done to confirm the diagnosis. Other causes can be ruled out by doing a colonoscopy. Do not neglect this symptom and get evaluated early to prevent complications. Meanwhile, consume lot of green leafy vegetables and other food rich in iron like fresh fruits, dates, jaggery. Drink plenty of water. Wish you a speedy recovery. Regards,
