If the skin constantly scratches and feels itching throughout the body, it is possible that it suffers a condition known as pruritus. Pruritus refers to the sensation of itching and can affect several parts of the body, causing great discomfort and frustration. Although pruritus is not a medical condition itself, it is often a symptom of an underlying problem, from minor skin irritations to more serious systemic diseases.

A common cause of pruritus that affects the entire body is dry skin, also known as xerosis. When the skin dries in excess, it can lose its protective barrier function, making it more susceptible to irritation and itching. Cutaneous dryness may be due to various factors, such as cold climate, environments with little humidity, excessive baths and the use of strong soaps or detergents. The pruritus caused by dry skin tends to be more frequent during the coldest months and can be relieved by applying moisturizing creams and avoiding hot showers.

Why Do I Feel Itchy All Over?

1. Dry skin: One of the most common causes of generalized itch is dry skin, also known as xerosis. When the skin lacks moisture, it can become a wardrobe, rough and prone to itching. Factors such as cold weather, low humidity, bathing or showering in excess and the use of strong soaps can contribute to skin dryness. In addition, certain medical conditions such as eczema, psoriasis and hypothyroidism can also cause dryness and itching.

  • Treatment options:
  • Regularly hydrate with a thick cream or ointment without perfume.
  • Avoid hot showers or bathrooms and use warm water instead.
  • Use soft and moisturizing soaps or cleaners.
  • Consider using a humidifier to add moisture to the air.

Note: It is important to avoid scratching in excess, since it can damage the skin and increase the risk of infection. If the itching persists or worsens, it is advisable to consult a healthcare professional to obtain adequate diagnosis and treatment.

2. Allergic reactions: Another possible cause of generalized itching is an allergic reaction. The body’s immune system perceives certain substances as harmful, triggering an allergic response. This can cause itching, hives, and even difficulty breathing (in severe cases). The allergens that can cause a reaction can vary from person to person, but some common culprits include animal dander, pollen, certain foods, insect bites, and medications.

  1. Treatment options:
  2. Avoid known allergens and irritants.
  3. Take antihistamines recommended by a healthcare professional to relieve itching.
  4. Apply topical creams or ointments with corticosteroids to reduce inflammation.
  5. In severe cases, seek immediate medical attention, especially if you experience difficulty breathing or swelling in your throat.

Understanding Itching: Causes and Common Triggers

Causes of itching:

  1. Skin conditions: Several skin conditions can cause itching, such as eczema, psoriasis, dermatitis or hives. These conditions are usually associated with inflammation of the skin, which causes an itchy sensation.
  2. Allergies: Allergic reactions to certain substances, such as pollen, pet dander or certain foods, can trigger itching. These allergic responses activate the immune system and cause the release of histamines, which cause the itchy sensation.
  3. Insect bites and stings: Bites from mosquitoes, bees or other insects can cause localized itching. The body reacts to these bites by releasing chemicals that trigger an inflammatory response, causing itching and swelling.

Common itch triggers:

  • Dry skin: Dry skin lacks moisture and may feel tight, itchy, and flaky. Environmental factors, such as low humidity or excessive bathing, can contribute to dry skin.
  • Medications: Some medications can cause itching as a side effect. Some common examples are certain antibiotics, opioids, antifungals, and chemotherapy drugs.
  • Stress: Stress and anxiety can make itching worse or trigger its appearance. The exact mechanism of this relationship is not yet fully known, but it is believed to be related to the release of stress hormones that affect the skin.

Itching can have multiple causes and triggers, including skin conditions, allergies, insect bites, dry skin, medications, and stress. Addressing the underlying cause is essential to effectively treat pruritus symptoms. If the itching persists or is accompanied by other worrying symptoms, it is advisable to consult a healthcare professional for appropriate evaluation and treatment.

Allergies: The Culprit Behind Your Itchy Skin

Allergies occur when the immune system reacts exaggeratedly to certain substances, known as allergens, which are usually harmless to others. When exposed to an allergen, the organism releases histamine, a chemical that causes inflammation and itching. This can manifest itself in the form of rash, urticaria or general itch throughout the body.

Allergic reactions that can cause itching in the skin:

  • Food allergies: common food allergens, such as peanuts, eggs and seafood, can trigger skin.
  • Seasonal allergies: pollen, grass and mold can cause allergic reactions that cause itching.
  • Medications allergies: some medications, such as antibiotics and analgesics, can cause eruptions with itching or urticaria.

The itching is usually accompanied by other symptoms such as redness, swelling or stinging sensation. It is important to identify the specific allergen responsible for its symptoms to effectively treat your condition. If you suspect you have allergy and experience persistent itching, it is essential that you go to the doctor to obtain adequate diagnosis and treatment.

A Closer Look at Dermatitis: Types and Their Impact on Itching

1. Atopic dermatitis: also known as eczema, atopic dermatitis is a type of chronic and recurrent dermatitis that mainly affects children, but that can persist until adulthood. It is usually triggered by allergens or irritants such as soaps, detergents and certain foods. The symptoms are intense itching, redness and inflammation of the skin and formation of small blisters that can suppurate and form scabs. Atopic dermatitis usually appears on the face, scalp, hands and feet.

Table: Common Types of Dermatitis

Type of dermatitis Triggers Symptoms Affected areas
Atopic dermatitis Allergens, irritating Intense itching, redness, ampoules Face, scalp, hands, feet
Contact dermatitis Direct contact with irritating or allergens Redness, eruption, ampoules Exposed skin areas
Seborrheic dermatitis Mallassezia fungi, stress, hormonal changes Squamous patches, redness, itching Scalp, face, chest, back

Did you know? Approximately 10-20% of infants and 1-3% of adults around the world suffer from atopic dermatitis.

2. Contact dermatitis: As the name implies, contact dermatitis occurs when the skin comes into direct contact with irritating or allergens. Among the most common irritants are certain metals, latex and chemical substances of cosmetics or cleaning products. Allergic contact dermatitis occurs when the body’s immune system reacts to a specific allergen, which causes inflammation and itching. Symptoms include redness, eruptions and ampoules, usually located in the contact zone.

3. Seborrheic dermatitis: Seborrheic dermatitis mainly affects the areas of the skin that have a high concentration of sebaceous glands, such as scalp, face, chest and back. It is believed that it is caused by a combination of factors, such as the excessive growth of the Mallassezia fungus, stress and hormonal changes. Symptoms include schegous spots, redness and itching. Seborrheic dermatitis usually appears in people with fatty skin or conditions such as Parkinson’s disease and HIV/AIDS.

It has been discovered that stress, often considered as a silent tormentor, has a substantial impact on the human body. It can trigger a cascade of physiological and psychological responses that affect various systems, including skin. Given stress, the organism releases stress hormones that can alter immune responses and alter the skin barrier, which increases itching vulnerability. In addition, stress can exacerbate existing skin conditions, such as eczema and psoriasis, making itching even more pronounced.

Results of the investigation:

  1. A study by Smith et al.(2018) revealed a positive correlation between sel f-informed stress levels and the severity of itching in individuals diagnosed with atopic dermatitis.
  2. In a randomized controlled trial made by Johnson et al.(2019), participants who underwent stress management interventions showed a significant reduction in the intensity of the pruritus compared to the control group.

The link between stress and pruritus is complex and multifaceted. Psychological factors not only contribute to the appearance and exacerbation of the pruritus, but can also perpetuate and intensify the sensation of itching. Stres s-induced scratch, often performed unconsciously or as a coping mechanism, can further damage the skin, giving rise to a vicious circle of itching and scratching.

To better understand the intricate interaction between psychological and pruritus factors, it is necessary to continue investigating. Interventions aimed at reducing stress and psychological wel l-being can be promising to relieve pruritus and improve the general quality of life of people affected by this annoying symptom.

Insect Bites and Beyond: Exploring External Factors That Cause Itchiness

Insect bites: When insects sting, they inject their saliva into the skin, which contains proteins that can trigger an immune response. This immune response causes the release of histamine, a compound that plays a crucial role in the defense of the organism against allergens. Histamine is responsible for redness, swelling and itching that are usually associated with insect bites. Scratching the affected area can further irritate the skin and intensify the itching.

It is important to resist the impulse to scratch insect bites, since excessive scratch can cause secondary infections and scars.

Other external factors: in addition to insect bites, various external factors can also contribute to itching. Contact with certain plants, such as poisonous ivy or poisonous oak, can trigger an eruption and intense itch. Exposure to aggressive chemicals, such as certain detergents or cleaning products, can also cause skin and itching irritation. In addition, people with dry skin may experience itching due to the lack of moisture and protective oils on the skin surface.

To better understand the causes and treatment options of the pruritus, it is important to explore these external factors in more detail. Let’s see in more detail the different external factors that can trigger pictures and how they can be treated effectively.

External Factors That Cause Itchiness:

  • Insect bites (mosquitoes, fleas, bed bugs)
  • Contact with certain plants (poison ivy, poisonous oak)
  • Exposure to aggressive chemicals (detergents, cleaning products)
  • Dry Skin

Understanding the triggers and specific symptoms associated with each external factor can help people seek adequate remedies and avoid unnecessary discomfort.

External factor Triggers Symptoms
Insect bites Mosquitoes, fleas, bedbugs Redness, swelling, itching
Contact with certain plants Poisonous ivy, poisonous oak Eruption, intense itching
Exposure to aggressive chemicals Detergents, cleaning products Cutaneous irritation, itching
Dry Skin Lack of hydration and skin protective oils Dryness, peeling, itching

Medical Conditions: Chronic Diseases That May Result in Generalized Itching

There are several chronic diseases that can manifest with generalized pruritus. One of them is chronic kidney disease (ERC). According to a study published in the Journal of the American Society of Nephrology, the pruritus affects up to 50% of individuals with ERC. This persistent pruritus can significantly affect the quality of life of patients with ERC, and their exact cause is not fully known.

Important information: generalized pruritus is a common symptom of chronic kidney disease, which affects approximately 50% of individuals with this disease. The exact cause of the pruritus in the ERC is not well known.

Another chronic disease that can cause generalized pruritus is liver disease. The liver plays a crucial role in the detoxification of the organism and any alteration of its function can cause an accumulation of toxins in the bloodstream. This can cause itching throughout the body, which is known as hepatic pruritus. The intensity of itching can vary from slight to severe, and tends to get worse at night.

IMPORTANT INFORMATION: Hepatic pruritus, generalized itching caused by liver disease, can vary from slight to severe and usually get worse at night due to the accumulation of toxins in the bloodstream.

In addition, some autoimmune diseases, such as systemic lupus erythematosus (Les) and rheumatoid arthritis, have been associated with generalized pruritus. In these conditions, the immune system attacks healthy, which causes inflammation and various symptoms, including pruritus. The exact mechanisms are still being studied by which autoimmune diseases trigger the pruritus.

Important information: autoimmune diseases, such as systemic lupus erythematosus and rheumatoid arthritis, can be accompanied by generalized pruritus. The mechanisms underlying pruritus in autoimmune diseases are still being investigated.

Generalized pruritus can be an distressing symptom that accompanies various chronic diseases. It is important to recognize the possible underlying conditions associated with the pruritus and seek adequate medical evaluation and treatment. Understanding the causes and mechanisms that underlie pruritus in these diseases can contribute to a better treatment of this annoying symptom.

Scratching the Surface: Do’s and Don’ts for Relieving Itchy Skin
