8 common triggers of itchy skin to be aware of

Are you constantly driven to scratch your skin due to an annoying itch? Do you feel helpless against the urge no matter how much lotion or cream you apply? Itchy skin can be incredibly irritating, but fortunately, it’s also a widespread problem, often associated with skin diseases. In this blog post, we look at some of the most common triggers that cause itchy skin and the steps to minimize them to alleviate the symptoms.

Eight common triggers of itchy skin


Excessive sun exposure
Excessive sun exposure can cause the skin to become itchy and inflamed due to the higher amounts of UV radiation. Those with susceptible skin may find that small doses of sunshine are uncomfortable and lead to breakouts, itching, and a prickly sensation. Not only is this bothersome, but it can also be potentially dangerous since people may be more likely to scratch or rub at the affected area and further damage their skin.
Many studies have found cancer patients complaining of itchy skin after radiation therapy using UVR. Hence, the studies conclude that UV rays from sunlight cause itchy skin. Therefore, it is advised to use antihistamines, sunscreens, and emollient creams.
To reduce itchy skin from sun exposure, one should use sunscreen with high SPF protection and limit their time outside when possible. Additionally, topical ointments or wipes may temporarily relieve sun-exposed skin irritations or diseases.

Age
Itchy skin and certain skin diseases like eczema can be annoying and uncomfortable, but it is even more common with age. As you age, your skin undergoes multiple changes, like becoming dry or being impacted by skin diseases like eczema or psoriasis.
As we grow older, our bodies produce fewer lipids to retain moisture in our skin, leading to lower hydration levels and causing barrier disruption. In addition, it triggers inflammatory responses like itching or flaking and intense sensitivity.
By ensuring adequate hydration, the right products can help protect your skin and keep it minimally reactive to external irritants.

Dry skin
Lack of moisture is one of the reasons for dry skin, which aggravates skin diseases and conditions like eczema. The common causes of dry skin include frequent hot-water baths, dry and hot climates, harsh chemical-heavy soaps, and exposure to intense sunlight. Chronic itch (that lasts longer than six weeks) due to dryness may indicate skin diseases such as atopic dermatitis and psoriasis.
To combat dry skin and itchiness, moisturize while reducing shower time, avoid extreme temperatures (hot or cold), limit using alkaline soaps, and wear loose clothing.

Chemical agents
Itchiness (a common symptom of skin diseases) is often caused by irritating particles in the air, such as chemicals, dust, or pollen. Chemical agents are notorious for inflaming the skin and triggering an unpleasant itch. Some of the common agents include:

  • Nickel (commonly found in stainless steel and other jewels)
  • Artificial fragrances in deodorants, body sprays, and lotions
  • Household products, including floor cleaners and detergents
  • Beauty products such as hair dye, cosmetics, sunscreens, and moisturizers
  • The latex used in gloves, condoms, balloons, and baby bottles

Renal diseases
Renal diseases (or kidney diseases), like uremia, can be a troubling and debilitating group of ailments. One challenging symptom of this burdensome condition is itchy skin, ranging from mild to severe.
Uremia is a widespread illness caused by highly damaged kidneys that cannot filter poisons from the body. The back, limbs, and belly are the most typically affected areas. When someone is suffering from renal dysfunction, their ability to regulate nitrogen-rich substances and other minerals is interrupted, leading to dryness in the outer layers of the skin.
Seeking medical advice and attempting topical solutions are two popular choices for patients struggling with itchy skin due to renal diseases.

Hormones
Hormonal fluctuations are more predominant in women than men. Itchy skin can be an incredibly frustrating and uncomfortable experience that often occurs during hormonal changes like puberty and pregnancy. Our bodies are complex systems of hormones, so these imbalances can lead to inflammation, which manifests as itchy skin.
While certain moisturizers and lifestyle changes can help with the itchiness, addressing the root cause of your hormone imbalance is critical to genuinely finding relief from this symptom. Therefore, you must talk to a dermatologist if the symptoms persist.

Daily lifestyle
Factors such as food choices, stress, exercise, environmental allergens, and emotional states can play a role in causing itchy skin. Some lifestyle factors that can trigger itchy skin conditions are as follows.

  • Inadequate consumption of dietary fibers leads to the poor gut microbiota, which fails to regulate skin inflammation.
  • Frequent consumption of junk or processed foods promote inflammatory reactions.
  • Inadequate sleep or erratic sleeping habits decrease the melatonin production required for healthy skin.
  • High consumption of chocolates, crisps, and nuts causes itchy skin as they contain high levels of nickel.

Changing your meal plans or avoiding certain foods may help relieve the discomfort. Unfortunately, some stress-related itching cannot be avoided, so focusing on relaxation techniques and reducing stress levels is essential. However, exercise should be done in moderation to ensure that the body’s temperature doesn’t become too hot, which could cause excessive sweating and further irritation.

Systemic conditions
Several conditions in your internal organs may cause changes in body blood content, reflected in dry skin. Systemic diseases that cause itchy skin (and, possibly, a skin disease) include:

  • Chronic renal failure
  • Hepatitis
  • Cholestasis of pregnancy
  • Extrahepatic biliary obstruction
  • Iron deficiency
  • Hyperthyroidism
  • Diabetes mellitus
  • Hypothyroidism
  • Blood cancer

Wrapping up
Various factors can cause itchy skin, including contact dermatitis, dry skin, allergies, or skin diseases. Thankfully, there are many ways to treat itchy skin and prevent it from happening in the first place. Look for signs of early onset of a severe medical condition like diabetes or cancer, and check with a dermatologist if you’re experiencing recurring symptoms. With knowledge comes power, so keep these tips in mind when dealing with itchy skin or any skin disease!

Afib – Types, causes, symptoms, and management

Afib – Types, causes, symptoms, and management

Atrial fibrillation (Afib) occurs when the usually stable and regular electrical impulses in the heart’s upper chambers (atria) begin firing chaotically, causing them to quiver or twitch (fibrillate). This can cause blood accumulation and clotting in the atria. These clots can reach the lungs through the blood vessels and cause pulmonary embolism or can reach the brain, resulting in a stroke. Let’s look at the forms, signs, and causes of Afib and its treatment options: Types of atrial fibrillation Afib can be classified as one or more of these: First-diagnosed Afib: Regardless of symptoms or the number or length of episodes, this refers to individuals diagnosed for the first time with Afib. Asymptomatic Afib: This condition is also called silent Afib, given the lack of signs or symptoms. A random electrocardiogram (ECG) could reveal asymptomatic atrial fibrillation. Paroxysmal Afib: Two or more episodes of the conditions that spontaneously resolve within a week are categorized as paroxysmal Afib. Persistent Afib: This refers to two or more episodes of atrial fibrillation that last seven days or more. Long-term persistent Afib: If the condition persists for more than a year, it is referred to as long-term persistent Afib. Permanent Afib: This is a chronic condition that cannot be managed using common treatment options.

How to reduce sugar intake and manage blood sugar

How to reduce sugar intake and manage blood sugar

It is a known fact that too much sugar can be devastating for your health. When blood sugar is high, the body produces more insulin, which can lead to several health complications, including prediabetes and diabetes. So, you must cut down on sugar. Choosing healthy snacks and increasing fiber and probiotic intake can help. Moreover, regular exercise is essential. Here are a few tips to lower sugar intake and manage blood sugar levels naturally. Avoid carbohydrates A high intake of carbohydrates has a substantial impact on blood sugar levels. The body breaks down carbohydrates into sugars like glucose, which enters the blood. While the body requires glucose for energy, an excess can be harmful. As the amount of glucose increases, so does the amount of insulin produced by the body, leading to a greater risk of lifestyle disorders. Some foods with an abundance of carbs to stay away from are potato chips and donuts. Control your portion size If you are dealing with frequent blood sugar spikes, monitoring portion size can help. When you eat a large meal, blood glucose increases suddenly. To avoid this, eat smaller meals. You can opt for five to six small meals per day instead of two or three large ones.

Things to know about chronic kidney disease

Chronic kidney disease   occurs when there is a gradual failure of kidney function due to illnesses, genetics, etc. The kidneys’ main role is to filter waste matter and flush out excess bodily fluids, but advanced kidney failure causes fluids, electrolytes, and waste to build up in the body. Various factors must be understood to manage the condition, including the causes, symptoms, prevention tips, and more. Read on to learn more about chronic kidney disease. Causes of chronic kidney disease The main causes of chronic kidney disease are as follows: Diabetes When the body’s sugar levels are too high and become unmanageable, bodily organs stop functioning as normal. The first to be affected are the kidneys, leading to diabetes, which, in turn, affects the nerves, eyes, and heart.   High blood pressure This is when blood pressure against the walls of the blood vessels increases, and can lead to chronic kidney disease, heart attacks, and strokes. Hence, chronic kidney disease can also be caused by uncontrolled high blood pressure.   Genetics Chronic kidney disease can also be passed down through the genes. Therefore if someone in your close family has the condition, it is likely to be passed down to you.   Autoimmune disease Lupus nephritis is an autoimmune disease that causes swelling of the small blood vessels, which are responsible for flushing waste out of the kidneys.  Birth disorder Sometimes, certain malfunctions of the kidneys develop in the mother’s womb and can cause infections and kidney damage later on in the person’s life.   Other causes Kidney stones or tumors can cause kidney damage or failure if not treated in time.  Glomerulonephritis It is a group of diseases that can cause inflammation in the filtering segments of the kidneys.
