Similarities between diabetes mellitus and diabetes insipidus?

Answer 1

The previous answer was: "thirst and increased micturation", which is entirely unhelpful and not even truly an answer to the question that you've posed.

Diabetes Insipidus is a disturbance of the body's water metabolism, which results in excessive excretion of heavily dilute urine. It can be caused by damage to the pituitary gland, or by a failure of the kidneys to properly utilize the hormone ADH. In addition, it can be caused by excessive water intake. Symptoms include an unquenchable thirst, polyuria, nocturia, dehydration, constipation, and dry skin.

Diabetes Mellitus, on the other hand, deals with the body's glucose levels and utilization. It is characterized by persistent hyperglycemia, which is caused either by insufficient insulin production (Type I) or by a failure of the body to react properly to insulin (Type II).

Answer 2

Similarities

1. High fasting glucose (fasting blood sugar) levels if no tight glycemic control
2. High Hemoglobin A1c levels if no tight glycemic control
3. Have genetic/hereditary implications
4. Have implications with gestational diabetes during pregnancy

Differences

Type 1 Diabetes:

• usually onsets earlier in life: birth to adolescence
• genetic predisposition more likely the cause
• pancreatic beta cells either not producing enough insulin or produce ineffective insulin protein
• usually need to take intravenous insulin medication
• usually results in diabetic ketoacidosis than hypoglycemic episodes

Type 2 Diabetes:

• usually onsets later in life: adolescence to adulthood
• environmental (diet/obesity) factors more likely the cause
• producing enough insulin, but the body cell's receptors do not have a sufficient response and therefore do not remove glucose from the bloodstream
• usually do not need intravenous insulin medication
• usually results in hypoglycemic episodes rather than diabetic ketoacidosis
