Insulin causes changes in the metabolism of carbohydrate and fats in particular. Insulin is important in the human body as it regulates the level of blood sugar, which fluctuates with food intake. It also promotes the uptake of amino acids by the cell and increases protein synthesis. It is impossible to dissociate these actions and while there may be some gain in muscle, there will also be an increase in fat levels.
There are risks in the use of insulin. The most likely problem is hypoglycaemia, a lowering of the blood sugar to a level where there may be an abrupt loss of consciousness and the individual collapses. Using this substance is particularly dangerous for a person who may drive a car, work near machinery or at heights.
Hypoglycaemia is recognised by a feeling of faintness, sweating and a shaky sensation. At times there is an onset of nervousness for no apparent reason. There is a sensation of confusion and uncertainty. At this time, some food should be taken to prevent further symptoms. If the diagnosis is wrong, no harm is done, but if a warning is ignored, the consequence may be disastrous for the loss of consciousness could be abrupt and this is too late for treatment. Attacks may differ from time to time and should never be taken lightly. Insulin is injected under the skin (subcutaneously) – not into the muscle. It is important that someone near you knows that you have used insulin and is aware of the effects and treatment of hypoglycaemia. These attacks may come on suddenly and without much warning. This is the reason why there is a need for someone close to you to know about the use of insulin and the treatment of its side effects.
