Which vitamin B should be taken for itchy skin?

For skin itching, one can usually choose to take oral vitamin E capsules to strengthen the repair of the skin barrier. Daily care should be based on moisturizing, actively investigating the factors that cause itching, monitoring blood sugar, avoiding spicy irritants, wearing cotton underwear, and providing symptomatic treatment such as itch relief. Oral medications like cetirizine tablets, moisturizing and itch-relieving capsules, and vitamin B1 tablets can be used. In the area of the skin that itches, topical applications like dampness-removing and itch-relieving creams and calamine lotion can be used to soothe the itching. Avoid using hot water for washing and excessive scratching. Pay attention to moisturizing skin care, and timely application of medical skin care products such as anti-itch moisturizing lotion after bathing. (Medication should be used under the guidance of a physician.)

How to treat high blood sugar and itchy skin?

Skin itching caused by high blood sugar requires a clear understanding of the cause of the itching. On one hand, it is mainly associated with elevated blood sugar levels, and on the other hand, it may be related to peripheral neuropathy caused by diabetes. A third consideration is secondary fungal or bacterial skin infections caused by high blood sugar. For these conditions, the first step is to test blood sugar levels. If a significant increase in blood sugar is found, it is important to adjust the existing sugar-lowering plan promptly to bring blood sugar levels within an ideal range. At the same time, medications that nourish the nerves, including cobamamide and vitamin B2, can be taken. For patients with secondary skin infections, appropriate antibacterial or antifungal ointments may be given. It is also important to maintain skin cleanliness and avoid eating spicy and irritating foods. (The use of medications should be under the guidance of a physician.)

Can I eat grapes if I have itchy skin?

Eating grapes is generally acceptable for skin itchiness. Grapes have a neutral nature and a sweet-sour taste. They are rich in glucose and fruit acids, and contain potassium, iron, phosphorus, calcium, and other trace elements as well as an abundance of vitamins. Traditional Chinese Medicine states that grapes have effects such as replenishing qi and blood, strengthening muscles and bones, generating seminal fluid, enhancing spleen and appetite, and promoting diuresis and reducing swelling. Clinically, there are very few cases of grape consumption causing allergic skin itchiness.

Causes of itchy skin on the lower legs in summer

In summer, if you experience itching on the lower legs, it's important to consider summer dermatitis. Summer dermatitis is a seasonal skin disorder caused by hot weather, commonly affecting adults' limbs, especially the lower legs. The outer side of the lower legs, or the front part, typically shows symptoms. The characteristics of the lesion include localized bright red erythema with dense, medium-sized papules. Scratching can lead to scratch marks, scabs, and significant discoloration, but generally, there is no erosion or exudation. The condition is clearly related to temperature and climate, so it typically improves when the temperature drops, and can be cured by autumn or winter. It is important to maintain a living environment with good ventilation and cooling, wear loose clothing, and keep the skin clean and dry. Treatment mainly involves topical remedies, including applying calamine lotion and washing with decoctions of traditional Chinese medicine.

What should I do if I have itchy skin due to a seafood allergy?

Seafood allergies can cause symptoms such as itchy skin and rash. You can take oral antihistamines, such as cetirizine or loratadine, to alleviate the symptoms. If the itching is severe, you can have intravenous treatments with dexamethasone, a large amount of vitamin C, and calcium gluconate, among other antiallergic treatments, to ease the symptoms. It is also advisable to drink plenty of water and eat fresh vegetables and fruits to supplement vitamins, which can be beneficial for recovery. Avoid spicy, stimulating foods and yeast-containing products, and be cautious with your diet to avoid allergenic foods. If necessary, go to the hospital to identify the specific allergens to clearly understand what you are allergic to, which will help in avoiding allergic reactions in the future. If the itching is severe and accompanied by obvious rashes, topical calamine lotion can be applied to the affected area for its anti-inflammatory, itch-relief, and astringent properties, promoting recovery. If the condition is severe, further medical examinations and treatments in a hospital are essential to prevent a serious condition from developing. (Use of medication should be under the guidance of a physician)
