what is the cause of irregular heart beat and dhydration and as well as anxiety uncontrollable emotions that threatens the health

[Jeffrey R Boris, M.D.]

Dear Baby,

Dehydration is the lack of adequate fluid intake for the body’s needs on a routine basis.  The lack of fluid in the system can cause the blood pressure to fall, which then causes the heart to speed up to try to keep the amount of blood flowing to the brain and body normalized.  The heart speeds up because the body puts out epinephrine, or adrenaline, to stimulate the heart rate.  However, it also can cause some other uncomfortable sensations, such as nausea, sweating, and a jittery feeling.  These sensations, plus that of the heart speeding up, can be scary and disorienting for some people, which then can lead to anxiety.  The anxiety can further lead to release of epinephrine, which perpetuates this cycle.  Anxiety is not typically threatening to health, per se, although the situations in which it can occur can be potentially problematic, such as if it occurs while swimming, rock climbing, or in other situations in which lack of concentration can cause the environmental effects to be personally overwhelming or risky.  Ensuring appropriate fluid intake on a daily basis, not skipping meals, and limiting caffeine intake is important to preventing this.

Anxiety disorder can also occur independently of dehydration; in this case, it is a psychiatric disorder and is not managed by a cardiologist.
