A. Hypersecretion of vasopressin
B. Hyposecretion of insulin
C. Hypersecretion of insulin
D. Hyposecretion of vasopressin

Answer 1

Hint: Diabetes insipidus is a disease or disorder of salt and water metabolism which results in intense thirst and heavy urination.

Complete Answer:
Diabetes Insipidus: Diabetes insipidus is a disorder that causes an imbalance in the fluids of the body. This imbalance leads to intense thirst. And also leads to producing large amounts of urine.

Causes of diabetes insipidus:
- Diabetes insipidus occurs when the body cannot properly balance the body's fluid's levels.
- When the body’s regulation system is working properly, then the kidneys help in maintaining this fluid balance.
- The kidneys filter the blood and remove the fluids from the bloodstream. These waste fluids get temporarily stored in the urinary bladder until the urination. The body also removes waste fluids in the form of sweating, breathing, etc.
- A hormone called Antidiuretic hormone or vasopressin regulates the excretion of these fluids.
- Antidiuretic hormone made in the part of the brain called hypothalamus. But it gets stored in the pituitary gland which is found in the base of the brain. Hyposecretion of this hormone causes diabetes insipidus .
- Because when we drink more and more water as in the case of diabetes insipidus the level of vasopressin falls in order to make the urine clear and diluted to remove more and more amount of water from the body.

Symptoms of diabetes insipidus:
- Severe thirst
- Heavy urination
- Dehydration
- Fever
- Trouble sleeping
- Vomiting
- Constipation
- Weight loss, etc.

Treatment for diabetes insipidus:
There is no cure for diabetes insipidus but it can be treated by medications. Treatments might include hormone therapy, drinking more water, a low salt diet, etc.

So, option D is the correct answer for this question.

Note: Diabetes insipidus can be diagnosed by the test of urine where doctors check that urine is concentrated or not. It can also be diagnosed by the blood test in which doctors measure the amount of electrolytes present in the blood.
