Is it a cold or allergies?


Ask the doctors

 Q. I feel like I have a perpetual cold all winter, every winter. I'm stuffy and sneezy and it never seems to get better. Do you think it could be allergies? How can I tell the differences?

 A. Colds and allergies produce many of the same symptoms: a runny nose, tiredness, and sometimes a sore throat. But they have different causes - a virus causes colds, while allergies are in immune system response to trigger substances, known as allergens. There are ways to distinguish one from the other. Colds sometimes produce a fever, but allergies never do. In addition, if you are suffering from allergies, you may also have itchy, watery eyes, symptoms that won't typically accompany a cold. But perhaps the biggest clue that can help you distinguish between a cold and allergies is the duration of symptoms. Cold symptoms rarely last more than two weeks, but allergies last as long as you are exposed to the substance that is triggering the reaction. So, if your "cold symptoms" appear at the same time every year and last for an extended period of time, the cause may very well be allergies. Many people with seasonal allergies will experience symptoms for six weeks at a time. If you are allergic to something in your home, such as dust mites, mold, or pet dander, your symptoms could get worse during the winter months, because the house is sealed up and fresh air isn't getting in. In addition, your heating system may be recirculating the allergen. Because your symptoms last for an extended period of time, it may be worth a visit to the allergist.

The lowdown on glycemic index and glycemic load

What are the facts about the glycemic load of foods? If you have diabetes, you probably know you need to monitor your carbohydrate intake. But different carbohydrate-containing foods affect blood sugar differently, and these effects can be quantified by measures known as the glycemic index and glycemic load. You might even have been advised to use these numbers to help plan your diet. But what do these numbers really mean---and just how useful are they? Glycemic index vs. glycemic load The glycemic index (GI) assigns a numeric score to a food based on how drastically it makes your blood sugar rise. Foods are ranked on a scale of 10 to 100. The lower of a food's glycemic index, the slower blood sugar rises after eating that food. In general, the more processed a food is, the higher its GI, and the more fiber or fat in a food, the lower it's GI. But the glycemic index tells just part of the story. What it doesn't tell you is how high your blood sugar could go when you

Making friends in your 50s and beyond isn't nearly as easy as it was when you were young. School and work provide the perfect opportunities to meet and interact with new people. Once you've retired, you might not have access to a robust social network. And if friends and family have moved away, your social circle can shrink even more. Yet it's never too late to seek out and develop new friendships. You just need to know where to look for them. The following are a few good places to start: Take up a hobby. Do you like to knit, paint, play bridge, or sing? Join a knitting club, take a painting class, join a bridge group, or audition for a chorus or musical in your area. Whatever your interest, there is likely a club for people who share it. Look to your local high school, colleges, community center, and senior center for programs tailored to your favorite hobbies.
