Recently, I developed an allergic rash.
I was worried because I couldn't find the cause.
Itching is usually caused by dry skin.
It may be itching caused by another condition.
I have summarized the causes that trigger itching.
I think this is good information to know.
△Dry skin
Dry skin is one of the most common causes of itching. There are several reasons why the skin becomes dry, and among them, first is dry air. Especially in winter, lower temperatures and humidity, along with indoor heating, make the skin even drier. During winter, it is helpful to use a humidifier set to above 50% humidity. Showering with hot water also causes the skin to dry out quickly. Therefore, it is better to take a quick shower with lukewarm water rather than very hot water, and when drying off after the shower, gently pat the skin with a towel to remove moisture.
Even when using soap or body wash with strong ingredients, they can strip moisture from the skin and cause dryness, so it is recommended to use gentle products with no fragrance and containing ceramide ingredients in moisturizers. These help trap moisture and restore the skin barrier. It is also advisable to use fragrance-free, gentle laundry detergents and fabric softeners.
△Allergic reaction
Itching may occur due to an allergic reaction to products that do not suit the skin. In such cases, antihistamines can help alleviate the symptoms. Applying a cold compress to the affected area can also be helpful.
△Sunburn or heat rash
If you do not apply sunscreen carefully or if you are exposed to sunlight without wearing a hat or sunglasses, you may get a sunburn, which can cause itching symptoms. In this case, taking a cool bath and applying aloe vera can help alleviate the symptoms. Wear light, loose-fitting clothing.
△Bug bites or stings
Not only when bitten by mosquitoes, but also when stung by bees or bitten by other insects, itching symptoms can occur. When inflammation occurs, applying a topical steroid can soothe the area. Cold compresses can also help, and most importantly, avoid scratching.
Reaction to medication
When taking a new medication, itching or other skin irritations may occur. In such cases, discontinue the medication and consult a doctor immediately.
Eczema
Eczema, a common skin condition, also causes itching in various parts of the body. Keep the skin well-moisturized and avoid factors that worsen the symptoms.
If an allergic reaction occurs after contact with a specific food or object, itching symptoms may develop. Taking an antihistamine and cooling the affected area can help alleviate the symptoms.
Age 65 years and older
After the age of 65, the skin becomes more sensitive to itching and irritation. Be sure to pay attention to moisturizing regularly with lotion and cream.
If itching persists for more than 6 weeks, it may be chronic... and could be a sign of other underlying conditions.
In some cases, skin-related symptoms such as itching may be caused by an underlying medical condition. Depending on the disease or cause, itching can appear on various parts of the body such as the hands, legs, or genitals. Persistent itching may be a sign of an underlying medical condition as follows.
△Liver Disease
According to a study published in 2019, many patients with chronic liver disease reported experiencing itching symptoms. The American Academy of Dermatology states that itching related to liver disease usually begins on the palms and spreads throughout the body. Not everyone experiences this, but itching is often observed in people with alcohol-related liver disease and non-alcoholic fatty liver disease.
△ Iron deficiency anemia or aplastic anemia
Itching may be a sign of iron deficiency or anemia. Although rare, people with iron deficiency or aplastic anemia may develop rashes due to anemia. In cases of anemia caused by iron deficiency, the skin becomes red and bumpy, and scratching may cause a tingling sensation. If aplastic anemia is the cause, small red or purple spots may appear under the skin.
Thyroid problem
Excessive or insufficient production of thyroid hormones can cause itching symptoms. When thyroid function declines, the skin becomes dry, flaky, and often itchy. Similarly, hyperthyroidism can also cause widespread rashes accompanied by itching.
Diabetes Mellitus
If you have diabetes, you are more likely to experience itching. This is because certain types of diabetes, such as diabetic polyneuropathy or peripheral neuropathy, can cause nerve damage. In such cases, itching may be limited to specific areas of the body, such as the hands, feet, or legs.
△Kidney Disease
Even with chronic kidney disease, itching can occur. In the early stages, symptoms may not appear, but as the kidney disease progresses, the skin becomes dry, flaky, and itching may develop. This itching, called uremic pruritus, occurs due to changes in the immune system or nerve problems. Itching tends to worsen at night.
△Specific cancer
Rarely, certain cancers such as leukemia, lymphoma, and skin cancer can also cause itching symptoms. In these cases, even if the skin appears normal, the itching affects the entire body.

서놔요즘들어 저도 목과 발목이 간지러워서 무슨 이유인지는 몰라서 일단 피부빌환 연고를 사서 바르고 나았어요 이런이유였을수 있겠네요 운동을 하며 땀을 많이 빼서 건저해졌거나 습진이였을수 있겠네요
하루=즐겁게+행복하게+웃으며✌갑상선은 처음들어보네요 간지러움 알러지 일줄 알았는데 , 종류가 엄청 많네요
프카쟁이엄마가 진짜 온몸의 가려움증을 겪고 계시는데 피부과에서 약받아서 먹으면 그때뿐 약 끊으면 또 가렵다고 하세요. 크림으로 보습을 열심히 하는데도 정확한 원인도 알 수없이 가려워하시니 휴... 걱정이 많습니다.
