Eye drops have less of a risk of side effects than do oral medicines, and such risk can be minimized by occluding the lacrimal punctum (i.e. pressing on the inner corner of the eye) for a short while after instilling drops. Eye drops are also used for stopping itching and redness of the eyes.
It is, therefore, not surprising that weight loss has become a very topical subject over the years, not only for the obvious cosmetic reasons but also due to increasing awareness of the health risks to people who are overweight. There have been proven links between people being overweight and the development of conditions such as type 2 diabetes, coronary heart disease and stroke as well as some cancers, such as breast and bowel cancer.
