insulin resistance

These depend on poorly understood variations in individual biology and consequently may not be found with all people diagnosed with insulin resistance.

1. Brain fogginess and inability to focus.
2. High blood sugar.
3. Intestinal bloating – most intestinal gas is produced from carbohydrates in the diet, mostly those that humans cannot digest and absorb.
4. Sleepiness, especially after meals.
5. Weight gain, fat storage, difficulty losing weight – for most people, excess weight is from high fat storage; the fat in IR is generally stored in and around abdominal organs in both males and females. It is currently suspected that hormones produced in that fat are a precipitating cause of insulin resistance.
6. Increased blood triglyceride levels.
7. Increased blood pressure. Many people with hypertension are either diabetic or pre-diabetic and have elevated insulin levels due to insulin resistance. One of insulin's effects is to control arterial wall tension throughout the body.
8. Increased pro-inflammatory cytokines associated with cardiovascular disease.
9. Depression. Due to the deranged metabolism resulting from insulin resistance, psychological effects, including depression, are not uncommon.
10. Acanthosis nigricans.
11. Increased hunger.

• Particular physiological conditions and environmental factors:
• > 40–45 years of age;^[5][6]
• obesity;^[5][6]
• your body storing fat predominantly in the abdomen, as opposed to storing it in hips and thighs.^[6]
• sedentary lifestyle, lack of physical exercise^[5][6]
• hypertension;^[5]
• high triglyceride level (Hypertriglyceridemia);^[5]
• low level of "good cholesterol";^[5]
• pre-diabetes, your sugar levels in blood have been too high in the past, i.e. your body has previously shown slight problems with its production and usage of insulin ("previous evidence of impaired glucose homeostasis");^[5][6]
• having developed gestational diabetes during past pregnancies;^[5][6]
• giving birth to a baby weighing more than 9 pounds (a bit over 4 kilograms)^[5][6]

The primary treatment for insulin resistance is exercise and weight loss. Low-glycemic load diet has also been shown to help.^[73] Bothmetformin and the thiazolidinediones improve insulin resistance, but are only approved therapies for type 2 diabetes, not insulin resistance. By contrast, growth hormone replacement therapy may be associated with increased insulin resistance.^[74]

Metformin has become one of the more commonly prescribed medications for insulin resistance, and currently a newer drug, exenatide(marketed as Byetta), is being used. Exenatide has not been approved in the UK except for use in diabetics, but often improves insulin resistance in healthy individuals by the same mechanism as it does in diabetics

Endocrinology

 the branch of physiology and medicine concerned with endocrine glands and hormones.

https://en.wikipedia.org/wiki/Endocrinology

Endocrinology (from endocrine + -ology) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones. It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction, and sensory perception caused by hormones. Specializations include behavioral endocrinology^[1][2][3]and comparative endocrinology.

The endocrine system consists of several glands, all in different parts of the body, that secrete hormones directly into the blood rather than into a duct system. Therefore, endocrine glands are regarded as ductless glands. Hormones have many different functions and modes of action; one hormone may have several effects on different target organs, and, conversely, one target organ may be affected by more than one hormone.
