The Rash to End All Rashes

Today’s topic is eczema. A lot of us have had eczema at one time or another or had a child who had it. The NIH says there are about 15 million people in the United States on a yearly basis affected by eczema. That’s not insignificant. Eczema tends to be more prevalent as a child. The good news is that it usually diminishes as we get older. But, as you know there are some people who have just a terrible time with eczema. My daughter didn’t get it classically as a infant. She was probably 7 or 8 before she got it. Then she had it horribly for a number of years. Some people get it when they get older. In some it doesn’t show up until they are adults.

What is eczema? It’s always interesting to look at some of the really big diseases that affect a whole lot of people. With all the billions of dollars that we do in medical research every year and all we think we know, a lot of times we still don’t know a lot about some diseases. Eczema is one of those that we don’t know why people get it.

Some people think skin allergens. Other people think dust mites. Others think chemicals. Part of it is probably a disordered immune response. It is just not well defined. It usually appears as a rash on kids on forehead, cheeks, forearms and scalp. On adults it’s a more classical case of appearing on the neck, elbows, knees and ankles. It looks a little different in adults and children.

The good news is that it’s not contagious. You don’t have to worry about catching it. The bad news is, if your mom or dad had it and your grandma and grandpa you’ll have some pretty good odds that you’ll have some trouble with it, too. There is certainly a genetic component to it.

Prevention ideas include trying to prevent coming into contact with whatever it is that is stirring you up first. If it’s wool, change to polyester. If there are a lot of dust mites in the home you try to change the environment. If there are chemicals, remove those. In the prevention/treatment arena you can moisturize those areas with lotions and creams to try to keep those physical things from encountering the areas of concern. At the same time moisturizing is believed to help eczema, not just prevent it. I can’t honestly say I’ve seen a lot of results from that when I’ve treated eczema, but that’s the first thing you want to do medically.

It’s interesting that sudden temperature changes seem to stir eczema up. It’s one of those observed phenomena that medicine doesn’t have a clue as to why that would be so. Sweating and overheating is thought to, but I see a lot of it in winter. One thing for sure is that we absolutely know that stress encourages and makes people with eczema get worse or pop out when they haven’t been having any trouble with it lately. Some people believe there are food allergies involved. Again, there is a lot we don’t know.

Next post I’ll talk about what we can do, medically, to treat eczema.
