Blood cortisol levels

Cortisol is a steroid hormone produced by the athline and also known as stress hormone. If a person is under intense stress, then cortisol levels in the blood will increase suddenly, if then high levels of cortisol can be the cause of some dangerous diseases.

1. What is Cortisol?

When the human body responds to a stress, the lower hill area secretes a hormone that releases the renal-directed hormone. This hormone stimulates the area before the carnation gland that secretes ACTH (ammonia-oriented hormone). Acth then stimulates the asteroid corisol type to convert sugar. Thus if the concentration of cortisol in the blood will increase due to the reverse conditioning mechanism to stimulate the still gland to reduce ACTH production, this is a valuable parameters for monitoring the function of the ang kidney coridenton.

Cortisol has the function of:


Chemical structure of Cortisol
  • Stimulation to form glucose
  • Stimulates degradation of the body's energy reserves
  • Help the body use sugar and fat to form energy
  • The body uses cortisol to respond to stress and dangerous cases that the body is aware of through the launch of sympathetic responses to stressors
  • Decreased inflammatory function and immune function
  • Stimulates the secretion of aerating acid

2. What is the blood cortisol test for?

The blood cortisol test is intended to check the level of cortisol production associated with certain conditions such as Cushing's syndrome and Addison's disease (angbilis). Your doctor will prescribe a test to measure cortisol levels in your blood when you have symptoms that suggest Cushing's syndrome or ang kidney failure as follows

Symptoms suggesting Cushing's syndrome:

  • Hypertension, hypertension
  • Obesity, especially abdominal fat, abdominal skin with purple stripes
  • Thin skin
  • Muscle atrophy and muscle weakness
  • Osteoporosis

Bone density measurement methods to detect the risk of osteoporosis

Osteoporosis symptoms warn of risk of cushing syndrome

Symptoms that suggest Addison's disease:

  • Weight loss, fatigue
  • Muscle weakness
  • Hypotension
  • Abdominal pain
  • There are dark patches of skin

3. What is the normal value of cortisol levels in the blood?

Cortisol levels in the blood are determined to be normal in the following value intervals:

  • 8am-12pm: 5.0- 25.0 μg/dL or 138-690 nmol/L
  • 12pm to 8pm: 5.0- 15.0 μg/dL or 138-410 nmol/L
  • 20pm to 8am: 0-10.0 μg/dL or 0-276 nmol/L

Increased blood cortisol levels if the above-mentioned range of values are exceeded may be due to a number of causes such as:

  • burn
  • Cushing's syndrome
  • Production of jerks
  • Hypertension
  • Armor
  • obesity


Cortisol levels in the blood change over time

If cortisol levels are lower than normal, there may be a number of main reasons such as:

  • Addison's disease (a upid renal failure)
  • Hypoth glucose
  • Impaired thyroid function
  • Liver disease
  • Post calving saline necrosis

4. Factors influential in blood cortisol test results

Some factors that may cause deviations in test results include:

  • Color cortisol levels change when the patient is exerted, when sleeping, or stress
  • Ruptured specimens of red blood cells
  • Patients with alcoholism or with an urgent pathology
  • Patients take certain medications that increase blood cortisol levels such as contraceptives, amphetamines, estrogens,… or reduce cortisol levels: androgens, barbiturates,…

Side effects of contraceptive collection

Women who use contraceptive pills can influence the test index of cortisol levels in the blood

Cortisol levels reflect your health and are the basis for diagnosing a number of dangerous diseases such as ango kidney failure and Cushing's syndrome. As soon as the body has unusual symptoms, you should go to a reputable medical facility for examination and advice from a doctor.
