7 Endocrine Disorders and Their Impact on the Skin

Endocrine disorders can cause a wide range of skin-related symptoms, which are often overlooked or misinterpreted. In this blog, we discuss some of the most common endocrine disorders, their impact on the skin, and dermatological treatment strategies.

Endocrine Disorders

The human endocrine system is responsible for producing many different hormones. These are made by various glands in the body, such as the pituitary, thyroid, adrenal glands, pancreas, testicles, and ovaries. They are necessary for processes like growth, metabolism, sexual function, reproduction, and dealing with stress and emotions. The number of hormones in the body can change, as new hormones and their variants are still being discovered and studied.

Endocrine disorders refer to conditions that arise from problems in the endocrine system, the collection of glands that produce and release hormones into the bloodstream. These hormones are chemical messengers that are essential for regulating various bodily functions, including metabolism, growth, development, sleep, and mood. When something goes wrong in this system, such as overproduction or insufficient production of hormones, it can lead to various health problems that can affect every organ and cell in the body.

Diabetes Mellitus

Diabetes mellitus can cause a variety of dermatological problems, with patients often experiencing xerosis, a condition in which the skin becomes extremely dry. This dryness can disrupt the integrity of the skin barrier, resulting in symptoms such as itching and the development of eczema. In addition, the reduced blood supply and increased glucose concentrations in the blood of diabetics can slow normal wound healing, leading to poorly healing wounds that are susceptible to infections.

Another common manifestation is diabetic dermopathy, which presents as light brown, scaly maculae, often localized on the lower legs. These lesions are the result of damage to small blood vessels that nourish the skin, a complication of the prolonged hyperglycemia that characterizes diabetes.

Granuloma annulare is a chronic skin condition often associated with diabetes. It manifests itself as ring-shaped or arc-shaped red bumps, primarily on the hands and feet. The exact cause is unknown, but it is thought to be related to an immune-mediated response in which an overproduction of certain cytokines plays a role, which can be exacerbated by hyperglycemia.

Acanthosis nigricans is characterized by dark, velvet-like skin tissue that mainly occurs in skin folds, such as the armpits and neck. This condition is strongly associated with insulin resistance, a common feature of type 2 diabetes. The excessive insulin in the blood stimulates the growth of keratinocytes and melanocytes, resulting in dark spots and thickening of the skin.

Necrobiosis lipoidica is a more serious skin condition characterized by thick, red lesions that may gradually transition into atrophic, yellow spots. The pathogenesis is complex, but involves the deposition of glycoproteins and lipids in the skin due to damaged blood vessels and chronic inflammation.

In addition, diabetic patients are susceptible to skin infections such as bacterial folliculitis, furunculosis, and candidiasis, due to the reduced immunological response and changes in the skin microbiota.

2. Hypothyroidism and Hyperthyroidism

The thyroid plays a crucial role in regulating various bodily functions, including the health of the skin. This gland produces hormones that directly influence the metabolic rate of skin cells, which in turn influences the hydration, texture, and overall condition of the skin.

Hypothyroidism, where the thyroid gland produces insufficient hormones, can lead to a range of skin symptoms. Patients may suffer from dry, cold, and sometimes pale-looking skin, often accompanied by swelling, known as myxedema. This condition can also lead to hair loss, brittle nails, and delayed wound healing. The standard treatment with levothyroxine aims to normalize thyroid function, which typically results in an improvement of the skin symptoms.

Hyperthyroidism, characterized by an overproduction of thyroid hormones, often manifests with warm, moist, and soft skin. Patients may also experience symptoms such as excessive sweating, skin rashes, and in some cases, redness and swelling around the eyes known as Graves’ ophthalmopathy. Dermatological care for hyperthyroidism patients involves managing these symptoms, often with beta blockers to reduce excessive sweating and corticosteroids for inflammation-related skin rashes.

Moreover, a disrupted thyroid function can contribute to other skin problems such as urticaria (hives), which presents itself as itchy, raised skin rash that can come and go.

3. Cushing’s Syndrome

In Cushing’s syndrome, an endocrine disorder characterized by excessive production of cortisol by the adrenal glands, various characteristic skin problems occur. One of the most common symptoms is a noticeable change in the texture and thickness of the skin. Due to the high cortisol levels, the skin becomes thinner and more fragile, resulting in increased susceptibility to bruising and injuries. Even slight pressure can already lead to bruising.

In addition, many patients with Cushing’s syndrome develop stretch marks on the skin. These stretch marks, which are typically wide, purple or dark red lines, predominantly appear on the abdomen, thighs, breasts, and arms. The high levels of cortisol cause a breakdown of collagen, an essential protein that gives the skin its firmness and elasticity. This loss of collagen leads to the appearance of these distinctive lines, which distinguish themselves by their size and color from ordinary stretch marks that can occur, for example, during pregnancy or weight gain.

4. Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome (PCOS) is a hormonal disorder that often leads to elevated levels of androgens (male hormones) in the body. This hormonal imbalance can cause various skin-related symptoms such as hirsutism, where women experience increased hair growth on the face and body. In addition, PCOS can also cause acne and seborrhea (a condition where the skin produces excessive fat).

These skin problems are directly related to the overproduction of androgens. For the treatment of these symptoms, oral contraceptives are often prescribed, which help in normalizing hormone levels. Anti-androgens such as spironolactone can also be used to counter the effects of increased androgen levels on the skin, by reducing oil production by the skin and reducing hair growth.

5. Acromegaly

Acromegaly is a rare hormonal disorder that results from an excessive production of growth hormone, usually by a benign tumor in the pituitary gland. This excessive growth hormone has profound effects on the body, including the skin. Patients with acromegaly often develop coarse facial features, with deeper forehead wrinkles and more pronounced facial folds. The pores in their skin can be remarkably enlarged, often accompanied by the development of acne-like comedones. Additionally, the eyelids can swell and become thicker.

Other dermatological symptoms of acromegaly include hypertrichosis, an abnormal increase in body hair, and hyperhidrosis, where patients sweat excessively. Also, the skin of patients can become remarkably oily, a condition known as seborrhoea. Hyperpigmentation can also occur, where the skin becomes darker in various places. The increased number of skin tags, small protrusions of the skin, is also a common symptom.

As for the dermatological treatment of these symptoms, chemical peelings and products with active ingredients such as vitamin A and niacinamide are often chosen, which help in improving the skin texture and reducing excess oil production. In some cases, surgical or laser treatments may also be needed to refine the structure and appearance of the skin and manage the aesthetic consequences of the disease. These treatments focus on softening the coarse skin features and treating the dermatological complications associated with acromegaly.

6. Primary Hyperparathyroidism

The parathyroid glands, also known as parathyroids, are small glands of the endocrine system located behind the thyroid gland in the neck. People usually have four parathyroid glands, each about the size of a grain of rice. These glands play a crucial role in the regulation of the calcium levels in the blood and bone metabolism through the production and release of the parathyroid hormone (PTH).

Primary hyperparathyroidism, an endocrine disorder often characterized by elevated levels of parathyroid hormone, can lead to complex skin symptoms, including itching and in severe cases the development of calciphylaxis. Calciphylaxis is a rare but serious condition where calcium accumulates in the small blood vessels of the fat and skin tissue, leading to ischemia and necrosis of the skin. This condition is particularly seen in patients with existing kidney problems and can cause extremely painful skin wounds.

From a dermatological perspective, the management of these complications involves the use of intensive moisturizers to reduce itching and dryness and protect the skin barrier. Specific wound care techniques are also necessary to promote healing and minimize infection risks in patients with calciphylaxis. Treatments may include the use of topical or systemic medication to control pain and improve blood supply to the affected areas. Interdisciplinary collaboration is crucial, with dermatologists, nephrologists, and endocrinologists working together to treat the underlying metabolic disorders and improve the patient’s overall health and quality of life.

7. Prolactinoma

Prolactinoma is a type of benign tumor of the pituitary gland that produces excessive amounts of prolactin. This hormone, which is mainly known for its role in milk production in women after childbirth. It can also cause significant skin changes when present in abnormally high amounts. In patients with a prolactinoma, symptoms such as acne and hirsutism may occur. Hirsutism refers to unwanted hair growth on the face and body, while acne can be aggravated by the hormonal imbalance caused by increased prolactin levels.

The treatment of a prolactinoma usually focuses on normalizing prolactin levels. This is often achieved with dopaminergic drugs, such as bromocriptine or cabergoline, which inhibit the release of prolactin by the tumor. These medications increase dopamine activity, which in turn reduces the production of prolactin. In addition to reducing the size of the tumor, these treatments can help restore hormonal balance and thus improve skin symptoms. Such therapies may result in significant relief from acne and reduction of excessive hair growth, thereby considerably improving the skin condition and overall well-being of the patient.
