Question: Hi doctor, my daughter of 18 years of age went to Europe last fall traveling to several countries for almost two months. She came back very constipated, this did not happened in the past when traveling for a month or so. Her doctor here prescribed her Metamucil and a stronger laxative which she should take three pill once a week if needed. Right now she is in Guatemala doing some volunteer work in eye clinics in small country side clinics. Last week on Monday she took those three pills and on Tuesday when she was observing an eye surgery she felt sick of her stomach and then lightheaded enough that she had to be help to sit down, she also said that she felt some tingling on one of her arms, yesterday I talked with her and she told me that she is feeling lightheaded in the evenings and also the tingling continues, both at the same time. She has been able to go to the toilet since she took the laxative and continues to take the Metamucil every day. Could the lightheaded feeling and tingling be related to dehydration? XXXXXXX
