Itching on the whole body might be a symptom of an underlying illness, such as liver disease, kidney disease, anemia, diabetes, thyroid problems, multiple myeloma or lymphoma. Nerve disorders. Examples include multiple sclerosis, pinched nerves and shingles (herpes zoster). Psychiatric conditions.
Allergic reactions to food, insect bites, pollen, and medicines. Skin conditions such as eczema, psoriasis, and dry skin. Irritating chemicals, cosmetics, and other substances. Parasites such as pinworms, scabies, head and body lice.
You should also visit your GP if your entire body itches and there is no obvious cause. It could be a symptom of a more serious condition. Your GP will ask you about your symptoms – for example, if you have noticed whether anything makes your itch worse, or if your itch comes and goes.
Dry skin: Your body loses moisture at night, which can make your skin itchy. Hormonal changes: At night, your body doesn't produce as many hormones as it does during the day and certain hormones reduce inflammation (swelling). As you have fewer hormones at night, your skin could be itchy.
Dry skin is a common cause of itchy skin without a rash. In most cases, dry skin is mild. It can result from environmental conditions, such as low humidity and hot or cold weather. It's also sometimes caused by activities that can decrease moisture in the skin, such as bathing in hot water.
Pruritus can be a symptom of an underlying condition. It has many possible causes; the most common being contacting an allergen, dry skin, pregnancy and your body's reaction to a medication. Pruritus can be chronic if your itching persists for six weeks or more.
Both vitamin B12 and vitamin A deficiencies may also cause itchy skin, so if you are experiencing chronically itchy skin, getting your level of these vitamins tested can be helpful. This testing will help determine whether these deficiencies are at the root of your skin sensitivities and itchiness.
It is important to recognize that there are many potential causes of itching and irritation other than pests. Allergies, cosmetics, medications, and environmental contaminants all can produce reactions similar to insect bites.
Are you feeling itchy or tingling all over the body? You may be experiencing a skin-related issue like dermatitis or eczema, an allergic reaction from a certain food or plant, or you may be having a symptom of anxiety or depression. Unexplained itching all over the body can also be caused by kidney disease or scabies.
Other causes
Itchy skin could also be due to more serious medical conditions. Nerve conditions caused by diabetes, pinched nerves, and shingles can cause severe itching. The skin condition psoriasis causes changes to the skin that can also produce itching and discomfort. Chronic kidney disease can also cause itching.
Scabies mites: When microscopic scabies mites burrow into human skin, they cause rashes and itchiness. A scabies rash looks like a cluster of bed bug bites, which makes it easy to confuse mite bites with bed bug bites. Unlike bed bugs, you won't be able to see scabies mites on your skin or in the bed.
Chronic itch is associated with increased stress, anxiety, and other mood disorders. In turn, stress and anxiety exacerbate itch, leading to a vicious cycle that affects patient behavior (scratching) and worsens disease prognosis and quality of life.
People with iron deficiency anemia may experience itchy skin (pruritis) that can become red, bumpy and sore when scratched. Rashes associated with aplastic anemia usually appear as tiny red or purple dots under your skin (petechiae).
Common dust mite allergy symptoms include sneezing, coughing, itchy eyes and itchy skin at night with the allergy often associated with asthma or eczema. For sufferers, the one place where they are most susceptible is the bed – as this is a favourite haunt of the dust mite.
Itching of the feet, legs or ankles is a common complaint in people with diabetes that may occur as a result of a period of too high sugar levels. Itching can range from being annoying to severe. Itching can be relieved through treatment, and may be eliminated if the underlying cause is treated.
When anxiety kicks in, your body's stress response can go into overdrive. This can affect your nervous system and cause sensory symptoms like burning or itching of the skin, with or without visible signs. You can experience this sensation anywhere on your skin, including your arms, legs, face, and scalp.
Stress rashes often appear as raised red bumps called hives. They can affect any part of the body, but often a stress rash is on the face, neck, chest or arms. Hives may range from tiny dots to large welts and may form in clusters. They may be itchy or cause a burning or tingling sensation.
Vitamin D. Studies have concluded that people who suffer from eczema and other similar skin conditions tend to have lower levels of vitamin D than the rest of the population. Taking a vitamin D supplement therefore increases your levels, helping to reduce the severity of itchy skin.
You may experience red, dry and itchy skin due to vitamin D deficiency. Intake of vitamin D can help you treat such skin problems. It can also reduce skin rashes. Vitamin D is also beneficial for treating eczema which is also a skin condition.
It's important to note that it isn't strictly true that magnesium does help itchy skin or that a magnesium deficiency causes dry skin. However, one of the many skincare benefits of magnesium is that it can help reduce the inflammation caused by conditions which lead to dry and itchy skin, such as eczema.
Zinc. Some natural health practitioners recommend zinc supplements to prevent or treat dry, itchy skin. Like turmeric, it may also be useful to help reduce persistent pruritus in people with kidney disease who are having dialysis treatment (iv).
