"Disease" is the label given to the various symptoms of chronic dehydration by the pharmaceutical companies so they can peddle their medications that do nothing but block the signals sent to the brain that an area of the body has developed a water deficiency. Medications have side effects that are often more dangerous than the problem they're designed to treat.
Histamine is a neurotransmitter in charge of water regulation. While it doesn't actually do anything to control the water itself, it signals the brain that a drought condition has developed and the brain then gives you a recognizable symptom to let you know that you need to drink water.
Medications work by blocking the signal sent to the brain by histamine. With no signal, the brain is fooled into believing that the problem has been corrected, and turns off the symptom. As soon as the medication wears off, however, and the signal is once again able to reach the brain, the symptom is restored.
A prime example of this in action is high blood pressure and cholesterol deposits in the arteries. Both of these events (and many others) are responses by the body to protect itself against damage. High blood pressure is a mechanism designed to prevent cell damage due to insufficient water and cholesterol buildup is designed to protect the tissues of the arteries from the damaging effects of acidic blood being forced through under high pressure.
95% of health problems not accredited to heredity or injury are connected to chronic dehydration. The average adult loses around 2 quarts of water per day through normal functions of the body but doesn't replace it properly. They mistakenly believe that "fluids" of any kind are an adequate substitute - and this is what the medical profession promotes. But there is no substitute for water and this is why things go wrong in the body.
