Iodine is essential to make thyroid hormones. Such hormones assist to keep cells healthy. The metabolic rate is also maintained. The body cannot synthesize iodine but needs it. It can be sourced only from the diet.
The compound is essential:
To treat conditions linked to excessive activity in the thyroid glands
To ameliorate radiation emergency linked with radioactive iodides use
To cure skin infection as a result of the Sporothrix fungus
Iodine is also seen to be beneficial in many cases:
Infection due to catheters: There is evidence that the application of povidone- iodine reduces blood stream infection risks for people suffering from hemodialysis catheters.
Pinkeye or conjunctivitis: There is sufficient research that solutions of povidone-iodine are more effective compared to silver nitrate when it comes to decreasing pinkeye risk in newborns. The compound, however, has been found to be not more effective than medications like chloramphenicol or erythromycin.
Foot ulcers for diabetics: The application of iodine to the foot ulcers are beneficial for individuals suffering from the condition linked to diabetics.
Endometritis or uterus inflammation: Application of povidone-iodine solution to vaginal area prior to Caesarian delivery reduces uterus inflammation risk.
Fibrocystic breast disease: The intake of iodine, more specifically molecular iodine, reduces the risk of painful breast tissue.
Mastalgia or breast pain: The intake of iodine tablets every day for a period of five months reduces tenderness or pain in women who suffer from breast pain linked to menstrual cycle.
Soreness and inside the mouth swelling: The application of iodine to skin prevents soreness and also swelling inside mouth as a result of chemotherapy.
Periodontitis or gum infection: Rinsing with the povidone-iodine solution during the non-surgical treatments could help in the reduction for depth of the infected gum pockets.
Surgery: Many claim that the application of povidone-iodine when surgery reduces infection risk. However, it is found to be less effective compared to chlorhexidine at the prevention of infections in surgical site.
