Electrolyte imbalance

Can kidneys get damaged due to dehydration:


If volume depletion is severe, GFR falls, but it has been thought to be completely reversible with hydration, unless ischemia results in acute kidney injury (AKI). Nevertheless, AKI is thought be largely reversible. Hence, dehydration has not been classically considered a risk factor for chronic kidney disease (CKD).

Vegetables are the best source of potassium; bone broth is a source of calcium and magnesium. The best acids are citrus juices, such as lemon juice, and vinegars, such as rice vinegar. Sea salt, or salty flavorings such as soy sauce or fish sauce, can provide sodium chloride. So the most basic food to take during a fast is a soup made of vegetables in bone broth, with salt and an acid added.

A palpitation describes the sensation that occurs when a patient feels an abnormality in the normal beat of the heart. Abnormalities in the electrical conducting system may cause the heart to beat too quickly, too slowly, or irregularly. Sometimes a palpitation may be a normal variant but it may also be caused by a significant problem that could be life threatening. A palpitation may be an isolated extra heartbeat or it may describe a run of many extra beats that run together for a prolonged period of time. Sometimes a missed beat or a pause can be felt.

Supraventricular tachycardia
Supraventricular tachycardia (SVT) is a general term that describes a rapid heartbeat that arises from electrical signals generated above the ventricle from within the atrium. It may occur due to outside forces acting upon the heart or because of “a short circuit” or abnormal wiring of the electrical conduction system.

SVT may be a normal physiologic response to a stress upon the body. When the body requires more oxygen delivery, the response is for adrenaline to be released and cause the heart to beat faster to increase blood circulation. This may occur as a response to exercise, illness, or injury.

Excess thyroid hormone or electrolyte abnormalities in the bloodstream may irritate the atria and precipitate SVT.
