When somebody has itching throughout ,we call it as generalised pruritis. This is a condition which can be acute which means it can be developed suddenly. Subacute, means it has been persistent for sometime, maybe 56 weeks to 3 months or chronic, where it lasts for more than 3 months. The causes of generalised itching, whether it is acute, subacute or chronic, they are going to be very different. In acute itching which is a sudden onset of itching, we are looking for any cause such as any new medicine which has been started or any new fever which can cause the itching, other any change in the products like harsher wash gel which can cause this or any new clothes could have caused this.So if you are looking at itching that has just started look for any associated rashes like mosquito bites and it can be treated very easily like eliminating whatever it is causing the itching, when it is subacute or chronic itching then the history becomes very important. So we have to know of there has been any dietary change that has been causing this, any change in the medicine especially that dry out the skin, that has been given to people to dry out the cholesterol, that can cause this dryness of the skin and then cause the itching or any chronic skin condition can cause the itching, for example fungal infection or even scabies could be causing the itching. Unfortunately when it is generalised itching, we have to not only look at any ski disease, we also have to look at any blood disease. Things such as jaundice, kidney problems thyroid problems, as well as liver dosage can cause the itching to come all over and last category of the disease can be skin disease like psoriasis, atopic dermatitis, seborrheic dermatitis, these are all various skin diseases that cause that can cause generalised itching. So if you have generalised itching I think the first thing you have to do is to identify whether any problem are there like if there is a change in routine or a new medicine and avoid that and if you have eliminated that and still it is persisting then it is better that you meet a dermatologist to get a better opinion and sometimes they will need to do blood tests as well to identify and treat you.
