Insulin production is impaired in type 1 diabetes and Insulin is given as an injectable drug; it can be used in later type 2 dm when natural Insulin levels diminish, though the role of Insulin in type 2 is much more complicated. ...Read more

My friend's sister has diabetes and she has an insulin pump. How exactly does it work?

My friend's sister has diabetes and she has an insulin pump. How exactly does it work?

Continuous insulin: The pump keeps a constant basal level of Insulin in the blood at all times. The person can also dial in a bolus dose at meal times to cover rises in blood sugar with eating. A good description of the pump can be found here http://www. Medtronic. Com/for-healthcare-professionals/products-therapies/diabetes/therapies/insulin-pump-therapy/index. Htm. ...Read more

But after many years of diabtes some type 2 can also need Insulin because their body stops making Insulin and they will then need insulin.

Could getting stabbed by a used insulin needle cause hiv?

Could getting stabbed by a used insulin needle cause hiv?

HIV: This is possible, but the needle would have had to been used by an hiv+ individual and you would then have had to have used it very shortly thereafter. If there is a major question in your mind you should be receiving prophylaxis and being tested for HIV with pcr for viral rna. Go and see someone with expertise in this area. Good luck and hope all is well. ...Read more

Iam diabetic since 2003 and stoped ameryl in 2007 to start lantus (insulin glargine) insulin then novo mix 30 in 2009 with metforal 850 what new pills now more effective?

There are a: Variety of different medication regimens that can be effective, but you need to couple them to diet, exercise and weight loss. The most effective metformin dose is 1000 mg twice/day. Multiple doses of rapid acting Insulin before meals and a basal Insulin such as glargine at bedtime is better than mixed insulin. Other oral therapies and injectable glp-1 agonists need to be discussed with your docto ...Read more

At what age can children learn to give themselves insulin injections safely?

At what age can children learn to give themselves insulin injections safely?

Really depends: It depends on when first diagnosed, many of the 1-2 year olds are so used to the injections given by their parents, that they ask to give it a try. I highly recommend that parents take a very proactive and supportive role in their child requiring insulin. By making it a normal healthy routine, the child will not fear it, but recognize its importance to keep the child safe & away from the er. ...Read more

Is insulin dangerous to a non diabetic? What would happen if you took some?

Is insulin dangerous to a non diabetic? What would happen if you took some?

Insulin is dangerous: Hi. Insulin exogenously administered is potentially dangerous to anyone. We (endocrinologists) use the "insulin tolerance test" to assess adrenal and growth hormone systems in certain cases. One-tenth of a unit of insulin per kilogram body weight is enough to make normal, non-diabetics hypoglycemic. So, small insulin doses could be taken with impunity (but WHY?), but bigger doses are DANGEROUS! ...Read more

How long does insulin last in a syringe?

Look at the insert: Most Insulin syringe manufacturers discourage the practice of keeping Insulin for a prolonged period of time in the syringes specially with long acting analogs like lantus (insulin glargine). I do tell my patients that it is ok for short acting insulins to be preloaded in a syringe if you are going out to eat but no longer than 2-3 hrs. ...Read more

Why do I have dark underarms and how can I get rid of them? They are a huge problem. I never want to wear sleeveless tops or dresses because of this. I scrub and they are still dark. Is it an insulin thing? I'm 5'6 and weigh 180. I lost 20 pounds recently

The: The dark skin under your arms could be acanthosis nigricans - a sign of Insulin resistance and type 2 diabetes. If this is the case, the best treatment is to treat the underlying disorder - Insulin resistance - which will then cause the dark areas to fade over time. You should give your doctor a call to discuss. They may want to do some screening blood work to assess whether you have pre-diabetes or type 2 diabetes and can work out a treatment plan for you. Typically, the first step is weight loss (congratulations on losing 20 lbs!) and your doctor can help with a diet and exercise plan along with giving you an ideal weight goal based on your height and build. Below, I've also linked to a website with additional information about acanthosis nigricans. Good luck! ...Read more

What exactly is the role of protein phosphatase-1 in insulin to insulin receptor interaction?

What exactly is the role of protein phosphatase-1 in insulin to insulin receptor interaction?

Complex interaction: Phosphoprotein phosphatase is activated by the insulin, which indicates that there is a high concentration of glucose in the blood. The enzyme then acts to dephosphorylate other enzymes. The net effect is for glucose to enter the cell where it can be metabolized andlalso lowers the serum glucose level. ...Read more

Why do you have to mix insulin before use my mom is diabetic and she wants to why she has rub the 70/30 insulin between her hands before she uses

Why do you have to mix insulin before use my mom is diabetic and she wants to why she has rub the 70/30 insulin between her hands before she uses

Many: Many types of Insulin do not need any mixing, rubbing. Those insulins that are cloudy are mixtures or suspensions that don't work well if not gently mixed.
In my view, these are inferior insulins that do not match your body's normal Insulin production. These mixtures tend to make you need to eat for the Insulin so as to avoid getting a low sugar. The better insulins also do not require mixing or rubbing. The main downside of these other "clear" insulins is that they cost more. Otherwise, they are superior in many ways.
