Heart problems immediately after enema? warming in my chest

Kay,

You are correct in that enemas can affect the electrolyte balance of the body, but that does take a little while to occur. Since this occurred almost immediately and also during a bowel movement, it is more likely to be a vasovagal episode.

Wikipedia describes this as: Among people with vasovagal episodes, the episodes are typically recurrent, usually happening when the person is exposed to a specific trigger. Prior to losing consciousness, the individual frequently experiences a prodrome of symptoms such as lightheadedness, nausea, the feeling of being extremely hot (accompanied by sweating), ringing in the ears (tinnitus), uncomfortable feeling in the heart, fuzzy thoughts, a slight inability to speak/form words (sometimes combined with mild stuttering), weakness and visual disturbances such as lights seeming too bright, fuzzy or tunnel vision, and sometimes a feeling of nervousness can occur as well. These last for at least a few seconds before consciousness is lost (if it is lost), which typically happens when the person is sitting up or standing. When sufferers pass out, they fall down (unless this is impeded); and when in this position, effective blood flow to the brain is immediately restored, allowing the person to wake up. Short of fainting a person may experience an almost indescribable weak and tired feeling resulting from a lack of oxygen to the brain due to a sudden drop in blood pressure.

There are many, many causes of a vasovagal episode. And, not everyone actually passes out.

Among the causes of this are dehydration (which can occur when using laxatives and enemas), digital rectal exams or dissimpactions, unpleasant or emotional experiences, certain medications or drugs, pressure around the throat and upper neck, pressure on the chest, valsalva maneuver or straining, and many more.

So, it is most likely that you had a vasovagal episode. If you are not feeling basically back to normal in the morning, then you may want to contact your physician.

Good luck.
