Heart pain - angina - is a sign of water shortage in the heart/lung axis.
It should be treated with increased water intake until the patient is free of pain and independent of medications. Medical supervision is prudent. However, increased water intake is angina's cure.
If you suffer from angina pain - that sudden, terrifying tightness in your chest that makes it difficult to move or even breathe - you've probably also been told you have coronary artery disease. Doctors will tell you it's cholesterol that's causing your arteries to narrow, and prescribe beta blockers and ACE inhibitors, balloon angioplasty or major, life-threatening surgery like coronary artery bypass.
But it's not cholesterol that is causing your pain. Angina is actually caused by dehydration. As prolonged drought sets in, your body becomes more acidic. Acid-like chemicals are produced that burn into the cell membranes in the linings of your arteries, causing painful angina spasms. Cholesterol actually plays a protective role, bandaging the damaged membranes and keeping them from peeling away. Only water can correct this acid imbalance and relieve the tortuous pain it causes.
