Q Is it possible to raise your IQ?

Intelligence is mostly hereditary. Intellectual ability grows until about age 16, and after that changes very little. Practicing various skills which are tested on IQ tests will increase your IQ score some, but it is not likely to increase your intelligence. Intelligence is basically the abilities to learn, to reason, to remember, to think abstractly, to problem-solve, etc. These abilities are very difficult to improve once you are an adult, though you may improve specific skills. E.g. you can improve basic mathematical skills by practicing them often and learning certain mathematical shortcuts, or you can learn to read faster by pushing your reading speed and learning to scan for meaning. Generally, the best way to improve your performance in specific work tasks is to do those tasks a lot. When you do that, you gradually learn the best possible techniques to efficiently and accurately complete that work, in the minimum necessary amount of time.

Q My baby has a white curd-like coating in the mouth. It bleeds when I try to clean it. What could it be? Is it normal?

Hello. The white coating you have described in your babys mouth could be a fungal infection! It is not normal. It could be acquired from the mothers birth canal at the time of birth and called as thrush in medical terms. It looks like elevated white patches of cheese or curd on tongue or cheeks and leaves behid a red bleeding surface when cleaned. Dont worry! It is not dangerous; but, it is surely painful for your baby and interferes with the feeding. In some babies the condition is self limiting and needs no treatment. In others an antifungal gel or medications might be needed.

Q My 10 year old daughter continues to wet the bed. Not every night, but i thought it would stop as she grows but still hasnt. I wonder if there is something medically wrong.

If you daughter has nocturnal enuresis sometimes, it may need further evaluation, as this is not so common in teenagers. There are some factors that may affect urine control in teens. These include excessive intake of caffeine drinks like tea or coffee, deep sleep pattern which can be a normal for growing teen, excessive emotional stress or fear of something, inconsistent sleep timings etc. These things can be corrected in order to fix the problem. Other things to give consideration are certain medications, diabetes of other medical diseases, family history of parents having the same problem, urinary tract infection, etc. If she is having this problem since her childhood, then this can be considered as primary nocturnal enuresis and she can be out of 2% of girls who continues with this till they reach their teen. This thing can be improved with proper counselling to her. Making her to use bathroom before going to bed. Limiting her fluid intake before going to bed. She can be effectively treated with moisture alarms while asleep. It will be less likely that she will need medications for this. Proper counselling and educating her may motivate her to take initiation to cure herself. You may take her to physician to rule out underlying disease if any.

For instance in the case of two people kissing, if both partners were to have large open sores in their mouths, or if they had severely damaged or bleeding gums then they might transmit the virus through the act of mouth to mouth kissing.

Q Me and my fiance had sex yesterday and today she had slight bleeding. What could be the reason for this??not planning for baby at this point of time!! Also we did use protection while having sex. And i am sure that i did not ejaculate inside. please guide

If you have taken protection assuming that it was condom and it was intact than no need to worry. For confirmation she can do urine pregnancy test after a miss period. If her periods were due she can have it early and start up with premenstrual symptoms. There can be many other reasons for premenstrual symptoms which include stress, infection, pelvic inflammatory disease, thyroid disease, anxiety etc. Slightly bleeding can because of friction during intercourse, hormonal imbalance, stress, anxiety etc.. Most probably she will be all right within few days if does not than I advise her to consult a gynac doctor who can perform physical examination and can guide her better.
