Adrenal Gland

Introduction

A system of ductless glands that secrete hormones is known as an endocrine gland system. In the blood, hormones are carried directly to their target organs as chemical messengers. As hormones are synthesized in certain tissues, they trigger a cascade of events that allow for certain cellular responses. Adrenal glands are located above the kidney. They are divided into regions cortex and medulla. Both regions produce hormones that regulate electrolyte balance.

What are Adrenal Glands?

The body contains two adrenal glands. These are located above each kidney. They are a part of our endocrine system. Despite their small size, the adrenal glands are quite important for your body’s hormone-related functions. As a result, elements that affect your adrenal glands may have a big impact on your general health. If you believe you might have an adrenal problem, see a doctor.

Location of Gland

The adrenal glands are endocrine glands that are located over the lateral surface of each kidney’s upper poles. The adrenal glands are located at the back of the abdomen, between the kidney and the ribs. They are triangular, and the parietal peritoneum only covers the front of them. The right gland is pyramid-shaped, while the left gland is moderately-lunar.

                                    

Hormones Secreted by Adrenal Gland 

• The gland’s outer layer is called the cortex. It generates both cortisol and aldosterone. The medulla is the gland’s most interior area. It generates both adrenaline and noradrenaline.
• Epinephrine, also referred to as adrenaline, is a hormone that responds swiftly to anxiety by quickening the heartbeat and raising blood sugar levels in the body. 
• Corticosterone controls the immune system and reduces inflammation in conjunction with hydrocortisone. 
• Cortisol: With the help of cortisol, the body controls and utilizes fats, protein, and carbohydrates. In addition, it weakens the immune system and affects physiology, which the body uses to help it cope with worry. 
• Aldosterone: helps the kidneys keep the blood and tissues of the body’s healthy salt chloride level. 
• Norepinephrine, also referred to as noradrenaline, works in conjunction with epinephrine to respond to anxiety. Its primary function is to prepare the body and mind for combat.

Function

• The adrenal glands are responsible for producing several hormones that help control blood pressure, produce several reproductive hormones, and maintain the proper level of salt in our blood and cells. 
• The adrenal glands’ release of stress-inducing hormones causes one of the most well-known reactions, the “conflict of the panic response.” 
• When and how rapidly an adolescent develops their reproductive system, helping during birth 
• Our endocrine system’s pituitary gland, also known as the “master gland,” controls our adrenal glands. The main controller of your endocrine glands is the pituitary gland, which is located inside your skull. Abnormal signals may interfere with the number of hormones your pituitary gland advises your adrenal glands to generate.

Disease-related to the Adrenal Gland

Adrenal gland dysfunction might manifest when 

• When your master gland is unable to efficiently regulate your hormone production, the adrenal glands may form benign or non-malignant tumours or harmful or cancerous tumours. 
• Can suffer from disorders of the adrenal glands. 
• People are born with particular gene diseases.

Cushing’s Disease

People with Cushing’s syndrome have excessive cortisol production from their adrenal glands. The most common cause of this is prolonged use of high dosages of corticosteroids. Lupus, arthritis, and pneumonia are just a few of the disorders that are treated with corticosteroids. They have cortisol-like effects throughout the body. 

Symptoms:

• The round face, the fat accumulation at the base of the neck, and the fat bulge between the arms.
• Skinny arms and thighs
• Gaining weight unnecessarily
• Prone to scarring skin
• On the hips, chest, and stomach, there are wide, violet stretch marks.

Addison Disease

A rare autoimmune ailment called Addison’s disease may develop when your adrenal glands don’t produce enough cortisol or aldosterone. This self-harm sickness may cause your immune cells to attack the tissues of your adrenal glands. 

Symptoms: 

• Arterial pressure is high despite the weight 
• Loss or gain without cause. 
• Hyperglycemia or intolerance to glucose 
• low amounts of potassium 
• Discomfort, stress, or panic episodes

Congenital Adrenal Hyperplasia (CAH)

Extremely little cortisol is synthesized in congenital adrenal hyperplasia (CAH), a genetic disease. Furthermore, persons who have this condition may also have additional hormonal issues in which their bodies create too much testosterone but not enough aldosterone.

Symptoms: 

• Early acne, body hair, beards, or loud voices (women)
• Rapid growth in children
• Sterility due to underarm hair

Adrenocortical Carcinoma

Adrenocortical carcinoma is a malignant tumour that often develops on the exterior of the adrenal gland. Oftentimes, this type of tumour is only found after it has spread to the body’s other systems over generations.

The adrenal glands are located above the kidney. Despite their small size, the adrenal glands are quite important for your body’s hormone-related functions. The gland’s outer layer is called the cortex. It generates both cortisol and aldosterone.

Frequently Asked Questions

1. Is it necessary to have both Adrenal Glands to Survive?
Ans. Since the adrenal glands are necessary for human survival, removing both of them (which is quite unusual) forces the patient to take medications and hormone replacements.

2. Is it Possible to live with just one Adrenal Gland?
Ans. Your doctor will administer painkillers to you. Your body can function regularly if your adrenal gland is working properly. If both of your adrenal glands were lost or if your remaining adrenal gland isn’t functioning properly, you might take medication every day to restore the hormones they were making.

3. Do the Adrenal Glands play a role in Digestion?
Ans. The adrenal glands release the stress hormone cortisone to inhibit bodily processes like the immune response and digestion that are not necessary for immediate survival.

4. What are Hormones that make us Drained?
Ans. The adrenal glands also create the hormone aldosterone, which is problematic since it helps regulate your body’s normal fluid and electrolyte balances. As adrenal depletion increases, it makes your body generate less aldosterone, which results in dryness and electrolyte imbalances.
