Thirst can have various causes, ranging in severity from 'minor' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose thirst, we could:
|Tendency Toward Allergic Reactions||20%||Unlikely|
|Rheumatoid Arthritis||1%||Ruled out|
|Alzheimer's Disease||1%||Ruled out|
|Adrenal Fatigue||0%||Ruled out|
|Cigarette Smoke Damage||0%||Ruled out|
How is your level of thirst generally?
Possible responses:→ I am (almost) never thirsty
→ Rarely thirsty
→ Average / sometimes thirsty / don't know
→ Frequently thirsty
→ I am (almost) always thirsty
Intense thirst and hunger are classic signs of diabetes.
Dry Mouth also suggests the following possibilities:
Hundreds of drugs list dry mouth as a possible side-effect. Antihistamines, decongestants, painkillers, muscle relaxants, and antidepressants are among the drugs that can cause dry mouth.
Radiation can damage the salivary glands and reduce the amount of saliva produced.
Smoking or chewing tobacco can reduce saliva production.
Excessive thirst (and resultant frequent urination) can be early warning signs of fluorosis.
