constantly upgraded. In fact, "diabetes" - a general term for conditions that cause increased urination. For diabetes insipidus characterized by excessive thirst and copious. Cause of the disease - a problem with a particular hormone or its receptor. Diabetes insipidus increases the risk of dehydration. What is a rare and "uncomfortable" disease?
What is diabetes insipidus?
Diabetes insipidus occur due to problems with the so-called antidiuretic hormone or its receptor. Antidiuretic hormone (ADH) is produced of the brain called the "hypothalamus" and stored in the pituitary. Release of ADH causes the kidneys begin to retain water and becomes more concentrated urine.
Usually when we are thirsty or a slight dehydration, the level of ADH in the blood rises. Kidney resorbed more water and more concentrated urine output. On the other hand, if we gulp drink two liters of water (do not try this at home), ADH levels fall. Urine will be light and diluted.
Diabetes insipidus can be caused by one of two problems related to ADH. One reason: too little ADH is produced, in this case, the condition is called central diabetes insipidus. Another reason: ADH is produced is sufficient, but the kidneys are unable to respond to the hormone. This renal diabetes insipidus.
Regardless of the form of the disease, the result is always the same. The kidneys can not do their job and hold water. Even when sick diabetes insipidus is suffering from dehydration, kidney will still excrete large amounts of dilute urine.
The inability of the kidneys to retain water gives rise to the symptoms of diabetes insipidus:
- Hyperdipsia
- Increased urination (polyuria)
- In some people, these symptoms adopt such dimensions, that the body is dehydrated.
The large loss of fluids can also cause electrolyte imbalance. Symptoms of this disorder include:
- Unexplained weakness
- Drowsiness
- Muscle aches
- Irritability
But why "insipidus"? The urine of people with this form of diabetes, tasteless. Can you not believe, but once upon a time doctors tried the taste of urine, to determine the type of the disease. Unlike diabetes, wherein the urine becomes a sweet taste, diabetes insipidus urine similar to fresh water.
How to diagnose diabetes insipidus?
People suffering from this disorder often go to the doctor because they are concerned about symptoms such as increased thirst and urination.
For the diagnosis of diabetes insipidus in a few hours taking serial blood and urine samples. During this time the patient can not drink anything, and the body is experiencing gradually increasing dehydration. After the allotted time is determined by the concentration of sodium in the blood and urine.
After that, the patient is administered a substitute for ADH to verify if it kidneys, making the urine more concentrated. Diagnosis is based on laboratory parameters and response to ADH.
