Are You Getting Too Many CT Scans?

CT scans have become a vital tool in medicine, using X-rays to create virtual “slices” of your body that help doctors diagnose everything from cancer to internal injury.

But about a third of CT scans are not necessary and needlessly expose patients to radiation, according to Health magazine, which recently took a closer look at the rewards and risks of medical imaging.

Dr. Roshini Raj joins TODAY to discuss the potentially cancer-causing radiation you’re exposed to with every scan and she says that you should talk to your doctor about whether any scan is necessary.

Why Your Period Might Change After Having a Baby

By Dr. Roshini Raj

As you know, your body changes drastically with each pregnancy, but it doesn’t stop at an expanding belly. For example, you produce about 100 times as much estrogen during a day of pregnancy as on a normal day. Other hormones, like progesterone and human chorionic gonadotropin, increase during this time as well. These temporary hormonal shifts alter your body not only during those nine months—they can have lasting effects, even after you’re done giving birth and have finished nursing.

This means that just as your breasts may never look quite the same again, your periods may become unrecognizable. Some women experience a pattern shift (differences in PMS symptoms, cramps, duration or heaviness, mood changes or all of the above) after their first baby, and then may go through another menstrual 180 after their second or third child. Still others have no changes at all.

Your period pattern may also undergo an adjustment in your late 30s as estrogen and fertility begin to decline. So your monthly deluge could be due to a combination of factors. If heavier bleeding or increased pain is making your periods harder to cope with, see your doctor; birth control pills can help even out your hormones.

    The Weird Reason Some People Are Allergic to Fruits and Veggies

The Weird Reason Some People Are Allergic to Fruits and Veggies

By Dr. Roshini Raj

While some studies have linked the rise in food allergies to exposure to particular pesticides over time, it’s very rare to have a true allergic reaction to the pesticide residues that can remain on produce. That said, allergies are very individual, and there’s no harm in trying out certified organic produce—which is free of synthetic pesticides—to see if that does the trick.

If going organic doesn’t help, though, it is possible to be allergic to the fruits and vegetables themselves. Some people have what’s called oral allergy syndrome, meaning they get reactions to certain proteins found in various fruits and vegetables.

For example, bananas, avocados, kiwis, and more can cause cross-reactions in people who are allergic to latex—an allergy you may not realize you have if you’re not, say, a health care worker or someone who wears a lot of rubber gloves. Those who have allergies to birch, ragweed, or grass pollens may react to things like hazelnut, peaches, celery, sunflower seeds, and zucchini, to name a few.

An allergist can do skin or blood tests to see which protein is causing your cross-reactions, and that can help you pinpoint foods to stay away from. Some people find that their symptoms occur only during allergy season or that they can, for example, eat apple pie without an issue but can’t bite into a fresh apple. That’s because cooking with high heat breaks down the problem proteins that cause the cross-reactions.

Itchiness may seem like a minor symptom now, but it’s very important to sleuth out your triggers with your doctor and avoid the ones that bring it on. Even if you’ve had only a mild reaction in the past, in rare cases your reactions could lead to anaphylaxis, a dangerous type of reaction that […]

Dizzy During Workouts? When to See a Doctor

By Dr. Roshini Raj

Dizziness is one of the trickiest symptoms of all because it can be caused by a variety of things, both worrisome and not. It may just be a sign that you’re dehydrated; make sure you drink enough H2O throughout the day (which means at least eight glasses) in addition to having water on hand during your workout to replace any fluids you sweat out. It could also be that you’re overdoing it. It’s great to push yourself a little in your gym sessions, but it’s not wise to go so hard that your head whirls. Try easing off a bit during workouts—going at a slower pace or doing fewer reps—to see if that solves the problem.

If you’re becoming dizzy even during light exercise, however, that’s a sign you need to see your doctor. Feeling the spins at the gym can be related to exercise-induced asthma. This typically causes shortness of breath or chest tightness as well, but if these symptoms are mild enough, you may not notice them. (You are working out, after all.) For that, your doctor can test your breathing strength and prescribe an inhaler to use before you hit the treadmill.

Finally, dizziness during a workout could signal an underlying heart problem, one of which is an abnormal rhythm, called an arrhythmia. There are a variety of types of arrhythmias—some make the heart beat too slowly or too fast, while others make the beats irregular. Arrhythmias can be caused by a structural problem, heart disease or even an electrolyte imbalance resulting from dehydration or poor diet. Sometimes exertion is the only time you get symptoms.

Depending on the type, arrhythmias are treated with prescription medications or surgery to implant a pacemaker. Another option is a procedure called catheter ablation, in […]

What You Need to Know About Dark Spot Correcting Creams

By Dr. Roshini Raj

My sun spots are out of control. Are those fading creams safe?

The reason the creams are controversial is that some of them contain hydroquinone. Though it’s the gold standard for nixing sun spots, hydroquinone was banned in some countries after animal studies suggested that it was a possible carcinogen. But note: The animals used in the studies ate large amounts of the chemical over long periods of time—which is not at all the way you would use it. Still, the FDA has asked for more studies in order to make sure it’s safe to keep on the market.

In the meantime, you can get a hydroquinone lotion over the counter or by prescription. It’s safe to do so as long as you follow some guidelines. First, don’t apply the cream more than twice a day for more than six months without consulting your dermatologist, even if you get it at the drugstore. Though the condition is pretty rare, prolonged use of hydroquinone may cause ochronosis, which leads to skin thickening and discoloration.

In some people, hydroquinone creams may also cause some irritation, so it’s a good idea to test the cream on a small patch of skin first and follow all instructions on the label. Depending on the specific cream, the package instructions may suggest, say, applying it twice a week at first before increasing to daily use.

Products with retinol (the active ingredient in many anti-aging products) can also help erase sun spots. So if you’re using retinol on your face, you may already have something in your medicine cabinet that should help. Keep in mind that hydroquinone needs to be used with SPF 30 because it can heighten sun sensitivity. Pregnant? Skip hydroquinone and retinol for now.

    Why Your Hands and Feet Are Always Cold and What to Do About It

Why Your Hands and Feet Are Always Cold and What to Do About It

By Dr. Roshini Raj

My hands and feet are constantly cold. I’ve heard people say that it’s from bad circulation, but that can’t be true, right? 

Actually, that’s not totally inaccurate. Your skin is kept at a comfortable temperature by your blood vessels, which distribute oxygen-rich blood throughout your body. When the mercury drops, sensory receptors in your skin alert your brain to constrict vessels. This allows smaller amounts of blood to your skin to conserve warmth in the trunk of your body, where all your organs are.

In some people, vasoconstriction, as this process is called, can be triggered by the slightest thermometer changes. And one study found that this type of reaction is more common in women, in part due to our fluctuating levels of estrogen, a hormone that plays a big role in regulating temperature. (So you’re not imagining it—you really are more sensitive to cold than your guy!)

A more severe cold sensitivity is a hallmark of Raynaud’s disease, in which extremities—usually just fingers and toes but sometimes also nose and ears—may turn white or blue and go numb. Depending on how bad your symptoms are, treatment may range from wearing extra gloves and socks to taking prescription meds that widen blood vessels.

Finally, cold hands may be a symptom of other conditions, such as hypothyroidism, lupus, or diabetes, or low levels of iron or a vitamin B12 deficiency. Your doctor can perform tests and prescribe the right medication, supplements or diet changes. But if cold hands are your only complaint, try warming them by staying hydrated and increasing your activity levels (get up from your desk at least every hour).
