Q: Fainting spells are not necessarily an indication of a serious medical condition. In fact, fainting spells may be caused by anxiety, fear, pain, emotional stress, hunger, dehydration, surprise, overexertion, clenching, spasms, choking, or drug and alcohol use. If you suspect that your fainting spells are being caused by one of these issues, there are measures you can take to prevent future episodes. Hydration is the best way to prevent fainting spells without medication. Drinking more water is ideal, but you can get fluids from food sources (like watermelon), milk, soups, etc. All caffeinated beverages, including sodas, should be eliminated. If you are sufficiently hydrated, you will be urinating regularly and your urine will be clear or light colored, not dark. Caffeine stimulates the heart, making fainting spells more likely to occur. If you drink large amounts of caffeine, you should cut back slowly to avoid headaches. While the amount of fluids you need each day depends on a number of factors including your level of activity, your climate, your overall health and whether you are pregnant or breastfeeding, you should drink about half of your weight in ounces each day. So if you weigh 200 lbs. then you should be consuming 100 oz (or 12.5 8-oz glasses) of fluids each day. If you are an athlete with more muscle-mass, you should drink about two-thirds of your weight in ounces. Eating regularly can also help to reduce lightheadedness and reduce your chance of fainting by boosting blood sugar. If anxiety and stress are causing fainting spells, calming techniques can help you avoid fainting spells. You can try counting your breaths or deep breathing, flexing and relaxing different muscle groups, and paying attention to the immediate moment rather than the past or future (also known as mindfulness). Avoid placing yourself in stressful situations and do your best to remove yourself from such situations. Learning to stay calm and to assert yourself can help you to overcome feelings of anxiety. The flushed look that many people get when they drink alcohol is actually blood rushing to the surface of the skin. This takes blood away from the brain, and can cause fainting episodes. Excessive drinking also causes dehydration, which is a leading cause of fainting spells. Illegal drugs, particularly stimulants such as cocaine or ecstasy, also cause fainting spells. These should be avoided.
A: Identify the cause. Prevent fainting spells through hydration. Practice calming techniques. Avoid excessive drinking and illegal drugs.

ESR and PV are usually elevated in people with multiple myeloma. They will also take a full blood count (FBC) to check for unusually low levels of red blood cells and platelets. You will need collect your urine in small amounts over a 24 hour period in sample cups. The sample will be tested for abnormal proteins caused by cancerous plasma cells, called monoclonal light chains or Bence Jones protein.

Q: You can help prevent skin cancer by wearing SPF. You should apply SPF 30 or more to any area of your body that will be exposed to the sun. Use about one ounce of sunscreen to cover your skin every time you apply it. You can wear a non-comedogenic moisturizer with sunscreen on your face to help your pores from getting clogged. In order to help prevent skin cancer, you should avoid going outside during the times when the sun is at its peak. This is typically between the hours of 10 am and 4 pm. This is because the sun's rays are most direct during this time of day. If you have to be outside, try to stay in the shade as much as possible. When you are going to spend a long time in the sun, you should wear protective coverings over your body. This means you should wear long pants, long sleeve shirts, hats, and sunglasses. This will limit unwanted UV radiation exposure to your skin. If you are not sure if your mole or skin area is skin cancer, make an appointment with your dermatologist. If you are at high risk, you should have regular exams with your dermatologist to keep track of it. If you have had severe sunburn recently, you may also need to get checked out. If your dermatologist is worried about a mole, you may need a shave biopsy to check the tissue.
A:
Use sunscreen. Avoid peak sun exposure times. Wear protective clothing. Talk to your dermatologist.
