May 7, 2013

Dr. Rania Mousa General Medicine
Starch iodine test is a test ordered to diagnose excessive sweating (hyperhidrosis) it is ordered by GP or family medicine doctor referred as necessary to a dermatologist or other doctor depending on the results and causes of hyperhidrosis.f you are suspected to have excessive sweating (hyperhidrosis),Your GP will ask you about your medical history to see if there is a genetic reason for your condition. Plus this is also done to see if you have an existing medical condition which may be causing excessive sweating.Your GP will then ask you about the symptoms of your condition,if your sweating affects all or parts of your body; and if you are currently taking any medication.
In regard to medication: there are some types of medication which cause excessive sweating as a side effect.if you are taking over the counter medicines then mention this to your pharmacist or your GP.then you will undergo a physical examination.The next step is to refer you for tests. Your GP will arrange for you to undergo blood and urine tests and possible referral to a dermatologist if necessary.and then if necessary couple of tests can be performed to determine the extent of your sweating. These include
1-Paper
This involves placing a piece of paper over the affected area of the body, e.g. armpits. The heavier and wetter this paper is the greater the extent of your excessive sweating.
2-Starch-iodine test
Starch is scattered over the affected areas of the body whilst the temperature around you is increased. This is done to trigger sweating. Iodine is then brushed over this starch. If the iodine turns blue then you have excessive sweating
The aim is for your GP to determine if you have primary hyperhidrosis or secondary hyperhidrosis.
if no apparent cause of your condition then you are said to have primary hyperhidrosis,if an existing condition is the cause or other factor such as your lifestyle, pregnancy,obesity or a particular type of medicine then you have secondary hyperhidrosis
