    Question:   My daughter is 2 years old. When she was 8 months we found out that she is severely lactose intolerant. I am mildly lactose intolerant. Is this a coincidence or is it genetic? What are the chances that my future children will be the same way? Is there a test that can be performed on newborns to check for lactose intolerance before they even leave the hospital?    Dr. McLaughlin's Answer

    Question:   I have a student who complains of problems with his vision when doing reading activities. He did wear glasses at one time but his vision is now supposed to be such that he doesn't need them. Two years ago his vision was 20/20. A recent in-school exam put it in the range of 20/26. I have noticed that when he has to read, his eyes become very red and aggravated. He has to rub them a lot and can only complete an activity for a minute or less. He says that he has the same problem watching TV but if he wears his old glasses it doesn't bother him the same. Do you have any suggestions?    Dr. McLaughlin's Answer

    Question:   Could you explain how dehydration might cause muscle cramps? Coaches often say NOT to drink water before strenuous activities to prevent cramps. Isn't that a contradiction?    Dr. McLaughlin's Answer
