How are diabetes insipidus and diabetes mellitus different?

Very different. Diabetes mellitus is the typical "diabetes" that we are familiar with. It's caused by an Insulin problem (too little or just not working well (resistance)) causing elevation in blood sugar. Diabetes insipidus is a water problem characterized by lots of urination and high sodium level. It's caused by an ADH (vasopressin) (antidiuretic hormone) problem (too little or just not working well).
Location of problem. Both causes frequent urination, however, diabetes insipidu (di) is different from diabetes mellitus (dm). Dm involves Insulin problems and high blood sugar. Di is related to how your kidneys handle fluids. It's much less common than dm. Urine and blood tests can show which one you have. Usually, di is caused by a problem with your pituitary gland or your kidneys.

Why is the urine of patients with diabetes mellitus bright (almost neon) yellow? Also, what causes the pH spike with diabetes insipidus?

Dehydration, fillers. Bright urine most often comes from dehydration (too little fluid or excess loss of fluids), often seen in diabetes. It can also come from the fillers and buffers in pills, including vitamins. pH spiking is alkalosis or excessively alkaline state from abnormal fluid and electrolyte dynamics. See your PCP or Endocrinologist for electrolyte lab work, and more info and discussion. Read more...

Is nephrogenic diabetes insipidus similar to diabetes in adult or is it very different?

Quite different. Diabetes (means running thru) insipidis(water) the terms together means the kidneys let water run thru, without reclaiming what you still need. The treatment involves lots of fluid intake and meds to keep your water from running out ( producing dehydration). Adults can have this problem, but the adult diabetes you note has to do with sugar (running thru) due to ineffective Insulin & different rx. Read more...

What is the difference between diabetes insipidus and mellitus?

Unrelated conditions. Diabetes mellitus (dm) is a condition of excessively high sugars which can cause one to void large amounts of urine frequently. Type 1 dm is caused by pancreatic failure so Insulin is required. Type 2 dm is resistance to Insulin or inefficient use. Diabetes insipidus is voiding large amounts of urine frequently due to either kidney or brain disorder, both unrelated to sugar & insulin. Read more...

What is diabetes insipidus?

Two types. Either antidiuretic hormone (ADH (vasopressin)) is not being made in the posterior part of the pituitary or ADH (vasopressin) is being made, but the kidney lacks the receptor to which ADH (vasopressin) is bound in order to work to preserve water from leaving the body in excess.

What do I do if I have diabetes insipidus?

See your doc. I am not sure how you know this is what you have, but if so you need to see your doc for treatments..Two types: one is deficiency of arginine vasopressin (a diuretic hormone--avp) and other is nephrogenic (kidneys not sensitive to avp). You will/should find out why having diabetes insipidus. But either way, you still will need treatment. Consult your doc... Good luck. Read more...
Follow doc's advise. You need to find out the cause so you can be treated appropriately. Often time, diabetes insipidus is just a symptom, not the cause. The hormone involved is ADH (vasopressin) (antidiuretic hormone). If the cause is in the brain, treatment is to give back ADH (vasopressin) (ddavp) either in nasal spray or pill. If the problem is at the kidney, treatment is antiinflammatory (indomethacin) and diuretics (hctz and amiloride). Read more...
