When a person wants to lose weight there are different methods of doing so. The first is to exercise and thus burn off the excess fat that is there in the body, the second is to reduce the consumption of calories. When the consumption is reduced, the body uses the fat that is stored in it to fuel the energy requirement and so a person loses weight and the third method which is the most painless of all is to resort to drugs to assist weight reduction.
In cases there are people extremely obese, which is they have a BMI of > 40 extreme workouts will not be possible and nor will it be possible to lose all that weight just by cutting down the consumption. These people do not benefit from the weight maintenance and conservative weight loss treatments. Therefore, there are 2 kinds of drugs which help these people lose weight. The first kind is those that increase the metabolism and burning of the fat that is present there for fuelling the needs of energy and the second is to restrict the absorption of fats in the body with the help of medicines like Xenical.
Xenical which is orlistat works by blocking out some of the fat that is eaten and prevents it from being absorbed by the body. This way Xenical helps in weight loss and reducing the risk of gaining back whatever weight has been lost already. Xenical needs to be combined with a diet that is low calorie and this helps people who are especially extremely obese as it helps them lose weight soon.
Xenical is only given to the people it has been prescribed for and therefore, before buying Xenical from an online pharmacy or even from a physical pharmacy, it is necessary that the patient who is prescribed Xenical must be done by either an online doctor or a doctor who the patient has visited. Xenical should be taken in the dosage prescribed by the doctor for the time period which the doctor mentions.
Xenical is usually prescribed three times a day with each of the main meals taken and the meals to be consumed should not contain more than 30% of fat. All doctors – be it, online doctors or physical doctors, one visit, keep reviewing the dosage and monitoring the weight of the patient on a regular basis and decide Xenical should still be continued.
If a person continues losing weight, the doctor may prescribe this drug even for 1-2 years or even more, based on how much weight the person still can lose and how much the person weighed at the beginning as well as the ideal weight the person should be at.
As Xenical restricts the fat absorption by the body to quite an extent, the fat-soluble vitamins like A, E, D and K are lesser absorbed by the body and so vitamin supplements need to be taken and that too the vitamin supplements need to be taken at least 2 hours prior to Xenical.
