If you manage your diabetes with one of the intermediate acting insulins, its variability from day to day might alarm you. Maybe you aren’t mixing it well enough.
This type of insulin takes one to three hours to start working and lasts for 12 to 16 hours. Its generic name is NPH; Novo Nordisk sells it as Novolin N and Lilly as Humulin N. NPH is also available premixed with short acting insulin.
But NPH insulin is itself a mixture, and that’s the problem. Its cloudy part is rich in insulin crystals while its clear part isn’t. Before you inject it, you have to mix these parts.
An insulin pen is a convenient way to inject NPH, and a typical recommendation is to “roll and gently shake 10 times” every time you use it. A study just published online ahead of print in the professional journal Diabetes Care shows that this isn’t good enough.

Definition An abnormal lack of sweat in response to heat may be harmful, because sweating allows heat to be released from the body. The medical term for absent sweating is anhidrosis. Alternative Names Decreased sweating; Anhidrosis Considerations Anhidrosis sometimes goes unrecognized until a substantial amount of heat or exertion fails to cause sweating. Overall lack of sweating can be life threatening because the body will overheat. If the lack of sweating happens in a small area only, it is usually not as dangerous. Common Causes Burns Certain genetic syndromes Certain nerve problems (neuropathies) Congenital disorders including as ectodermal dysplasia Dehydration Neurologic disorders such as Guillain-Barre syndrome Skin diseases that block sweat glands Trauma to sweat glands Use of certain drugs
Definition Sweat electrolytes is a test that measures the level of chloride in sweat. Although genetic tests have become important methods for determining whether a child has cystic fibrosis, the sweat chloride test remains important. Alternative Names Sweat test; Sweat chloride; Iontophoretic sweat test How the test is performed In the first part of the test, a colorless, odorless chemical that causes sweating is applied to a small area on an arm or leg. An electrode is then attached to the arm or leg, which allows the technician to apply a weak electrical current to the area to stimulate sweating. People may feel a tingling sensation in the area, or a feeling of warmth. This part of the procedure lasts approximately 5 minutes. The next part of the test involves cleaning the stimulated area and collecting the sweat on a piece of filter paper or gauze, or in a plastic coil. After 30 minutes, the collected sweat is sent to a hospital laboratory for analysis. The entire collection procedure ta...
