What affects tears production?
Tears production can be affected by allergies, medicines and certain types of health conditions. In some cases, the inflammation of the channels that provide these production may and eliminate tears. In most cases, insufficient tears production is treated with eye drops, but overproduction may require less surgery.
Most tears failures are related to insufficient production, but some people suffer from excessive tears. In some cases, this condition is caused by allergies. When the body is exposed to allergen, one of the most common reactions is for itching eyes and begins to be filled with tears. Another common reason for excessive tearing is to block tear channels. If this happens, it is sometimes necessary to open the pipeline surgically. When the eyelids look at the eyelids, the tears are excreted with small drains called Puncta located inside the upper and lower eyelids. Sometimes these drains become or infected, which can reduce the amount of liquid secretion. Sometimes can irritation caused by contact lenses or pollutantsEnvironmental substances cause these drains to increase, which also prevents tears from producing.
It is assumed that some health conditions, such as thyroid disorders and Parkinson's disease, affect tears production, causing a condition called dry eye syndrome. This syndrome is often chronic and patients suffering from this syndrome usually have to use eye drops several times a day to keep the eye sufficiently lubricated. In severe cases, doctors may perform less surgery to connect to tear pipes, so what the small liquid produced remains in the eye for a longer period of time.
common types of drugs that affect tears production are blood pressure medicines that contain diuretics, antihistamines. In addition, Decongestants and some Types antidepressants can also reduce the amount of tears produced. In most cases, when drug use is interrupted, tears are returned to normal.
tears that cover the eye contain a large amount of vitamin A and some studies indicate that those suffering from vitamin A deficiency are more likely to be insufficient tears production. In these patients, doctors sometimes recommend vitamin and increased eye drops. They may also recommend dietary changes that increase the intake of food -rich foods.
