anyone have any info on how dehydration affects people with HCM. I work outside for a living and dehydration is just part of life. My doctor told me to not get dehydrated. Thanks for any info..

Dear Ronnie

The heart resides in a liquid-filled pouch called the pericardium. The electro-chemcial reaction needed to pump your heart relies on potassium, magnesium, calcium and sodium. These mineral salts are the first things lost when you lose water. Dehydration can also lower your blood pressure and can affect the pericardium eventually.

Sports drinks contan high levels of these chemcials --called electrolytes. Gatorade, Sportade, etc. But they also have a lot of sugar. Glaceau water makes Smart Water that is water with electrolytes and no sugar.

Working outside shouldn't preclude you from getting enough water. They now make a water bottle that you wear like a back pack and it has a sippy straw so if you can't use your hands, you can still drink. Sports stores should have this, especially climbing or biking type stores.

It really is important to get enough water. You can also buy water bottle carriers with over the shoulder straps.

take care,

Hi Ronnie:

My son is 14 with HOCM.......what I can tell you is that when Derick has not drank enough he feels horrible. I encourage him to drink drink drink. Mostly water. When Derick gets a stomach bug.....its very scarey as he gets weak, dizzy etc. Thank God other than his heart, he's a very healthy kid other wise. I was glad that you mentioned it as it has always been a huge issue with him.

Take Care, Sue

HCM is a pathology which creates a "diastolic dysfunction." This means that when the heart is resting between beats, it cannot function as well as a normal heart would function. During the resting (diastolic) phase the left ventricle fills with blood from the left atrium. In a diastolic dysfunction it receives less blood than it would normally so it then has less blood to pump to the body when it beats. In dehydration the blood volume drops simply because of fluid loss, creating another situation in which the heart has less blood to pump with each beat..

Those of us with HCM face double jeopardy with dehydration. We will suffer many more symptoms because much less blood (and the oxygen & nutrients the blood carries to our tissues) is pumped to the body with each beat. The blood pressure will often drop, too, adding to the problem.

I myself live in a hot desert climate where dehydration is the norm for most people, just as it is for most people who work outdoors as you do. I have learned to drink sufficient water throughout the day to keep my urine very light yellow. Frequent trips to the toilet seem to me to be a fairly small price to pay to have fewer episodes of dizziness, visual distortions, and shortness of breath!

Good luck,

these explanations of dehydration are extraordinary. HCM patients never fail to amaze me with their ability to learn how to take care of their own bodies.

The overwhelming message here is drink drink drink drink drink (but not alcohol).

Best wishes and keep well hydrated.
