2Early warning signs may include: excessive thirst, frequent urination, weight loss, fatigue
3Subclinical changes in blood tests, blood pressure, or weight often precede overt symptoms

Conditions That Cause Both Excessive Thirst and Nausea

4 conditions are associated with this symptom combination

Type 1 Diabetes

Type 1 diabetes is an autoimmune disease in which the immune system destroys insulin-producing beta cells in the pancreas, requiring lifelong insulin therapy. It typically develops in childhood or adolescence and accounts for 5-10% of all diabetes cases.

Dehydration occurs when the body loses more fluid than it takes in. Even mild dehydration (1-2% body weight) can impair cognitive and physical performance.

Hypercalcemia is elevated blood calcium, most commonly caused by overactive parathyroid glands or cancer. Symptoms follow the mnemonic 'bones, stones, groans, and psychic moans'.

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a life-threatening complication of diabetes in which the body produces dangerously high levels of blood acids called ketones. It most commonly affects people with type 1 diabetes and requires emergency treatment.
