    Obesity is a medical condition in which a person has an excess of body fat. This creates a negative effect on its health.
    People are generally considered obess when their body mass index is over 30 Kg/m2
    Body Mass Index (BMI) is a measurement obtained by dividing a person’s weight by the squeare of the person’s height. It stimates how much you should weigh based on your height.
    The number we obtain is compared with values that are stablished: If it’s below 18’5 the person will be underweight; Between 18’5 and 24’9, healthy; 25-29’9, overweight; And as I said before if the value is over 30, a person is considered obese.
    However, this is not always the best option to decide if we need to loose weight. For example, in the case of body builders, they have a big amount of muscle. As we know, muscles weights more than fat, so their BMI will be higher. Other example are old people. We can say that having a slightly higher BMI will protect them from thinning of the bones (known as osteoporosis). So a slightly higher BMI can be good.
    But what causes obesity? Taking more calories than your body burns can leat to it. When this happens, the body stores unused calories as fat.
    The two main causes of obesity are overeating and physical inactivity. When we overeat, we gain weight, especially if the diet is high in fat. Foods that are high in fat or sugar, for example fast food, fried food and sweets have high energy density (lot of calories in a small amount of food). It is also important to talk about the frequency of eating. Scientists have observed that people who eat small meals four or five times daily, have lower cholesterol levels and lower and/or more stable blood sugar levels than people who eat less frequently (two or three large meals daily).
    Sedentary people burn fewer calories than people who are active. This is strongly correlated with weight gain in both sexes.
    Obesity can also be caused by genetics. A person is more likely to develop obesity if one or both parents are obese. Genetics also affect hormones involved in fat regulation. For example, one genetic cause of obesity is leptin deficiency. Leptin is a hormone produced in fat cells and also in the placenta. Leptin controls weight by signaling the brain to eat less when body fat stores are too high. If for some reason its production or its work fails, this control is lost and obesity occurs.
    There are also other factors that can make a person to be affected by the condition. For example, some diseases such as hypothyroidism, polycystic ovary syndrome or Cushing’s syndrome are also contributors to obesity.
    Some medications are associated with weight gain: Antidepressants, anticonvulsants or some diabetes medications.
    Heart disease and stroke, high blood pressure, Diabetes, some cancers, gout, oisteoarthritis and breathing problems (sleep apnea or asthma) are some of the conditions obesse people are more likely to have.
    So know we will be thinking how can it be prevented. First of all, follow a healthy veried eating plan rich in all nutrients . Making healthy food choices, keeping our calorie needs and the balance of energy in our body will help.
    Also is important to focus on the portion size. Many times we eat more amount than the one we actually need.
    Being active and reducing the screen time is decessive in preventing the condition. Make a personal active plan with activities that you will enjoy and try to do them frequently. As I said, reducing the screen time, which means the time we usually spent playing videogames of watching the TV. Health experts recommend 2 hours or less a day of screen time.
    In Czech Republic the adult prevalence rate was 32’7% in 2008. Czech Republic occupies the 46th place in the obesity Word Rank and the 4th place in the European Rank. From my point of view this is quite surprising due to the fact that Czech Republic is not a big country and is one of the fattest countries in Europe.
    You already know healthy eating can have a positive impact on your life, but just how far do these benefits extend? Evidence suggests regularly eating healthy, well-balanced meals contributes to sustained weight maintenance, a better mood, increased energy levels, positive inspiration to others and the potential for a heightened quality of life.

    Tumescent Liposuction
    The word tumescent refers to anything that is swollen and firm. In the tumescent technique for liposuction, a large volume of very dilute solution of local anaesthesia (lidocaine and epinephrine) is infiltrated (injected) into the fat beneath the skin, causing the targeted area to become tumescent, in other words, swollen and firm. The local anaesthetic lidocaine in the tumescent solution provides such complete local anaesthesia, that it eliminates the need for general anaesthesia, or IV sedation. The drug epinephrine (adrenalin) provides profound localized vasoconstriction that it virtually eliminates surgical bleeding during tumescent liposuction. By eliminating the risks of general anaesthesia and the risks of excessive surgical bleeding, the tumescent technique for liposuction totally by local anesthesia has eliminated the greatest dangers associated with the older forms of liposuction.
    Liposuction was initially developed in 1978-1982 in Italy and France, and introduced into the United States in 1982. At that time, liposuction could only be performed under general anesthesia, and was associated with so much blood loss that patients frequently required hospitalization and blood transfusions. In 1985, Dr. Jeffrey A. Klein, M.D., a dermatologist in California, revolutionized liposuction surgery when he developed the tumescent technique, which permits liposuction totally by local anesthesia and virtually eliminates surgical blood loss. Dr. Klein first presented the tumescent technique at a medical meeting in Philadelphia in 1986. The first publication describing the technique was published in the American Journal of Cosmetic Surgery in 1987. Because the tumescent technique is by far the safest form of liposuction, it has become the world wide standard of care. Not only has the tumescent technique proven to be safer than the older techniques that required general anesthesia, it has also proven to be less painful, has minimized post-operative recovery time, and has produced optimal cosmetic results.
    The tumescent technique is so effective at minimizing blood loss that the majority of patients lose approximately 15 to 30 ml (1 to 2 tablespoons) of blood during large volume liposuction. This is the same volume of blood that is taken for routine pre-operative laboratory studies. In the days before the advent of the tumescent technique, the biggest risk of liposuction was excessive loss of blood during surgery. In fact, many surgeons required their patients to donate their own blood several weeks before surgery, and then during surgery, the blood would be returned to the patient by transfusion. With the advent of the tumescent technique, blood transfusions are no longer a part of liposuction surgery.
    There is dramatically less bruising with tumescent liposuction totally by local anesthesia compared to other liposuction techniques under general anesthesia. There are two reasons for this significant decrease in bruising. First, because there is so little blood loss with the tumescent technique, there is almost no blood that remains beneath the skin to cause bruising after surgery. The second reason for decreased bruising is that with the tumescent technique there is a considerable amount of post-operative drainage of the blood tinged anesthetic solution. The incisions are so small (about 1.5 mm), the incisions do not require stitches. By allowing these wounds to remain open for two to three days after the surgery, most of the residual blood-tinged anesthetic solution drains out. This minimizes bruising and swelling and accelerates the rate of healing.
    There have been no reported deaths associated with tumescent liposuction totally by local anesthesia. Virtually all deaths associated with liposuction have been associated with 1) multiple unrelated surgical procedures performed on the same day (facelift, breast augmentation, hysterectomy, etc), 2) excessive amounts of liposuction or an excessive number of body areas treated by liposuction on a single day, 3) the use of general anesthesia or heavy IV sedation with narcotics. Liposuction is an extremely safe procedure provided the patient is not exposed to excessive surgical trauma, excessive narcotic analgesics, or prolonged use of general anesthesia.
    Local anesthesia used in the tumescent technique for liposuction is so effective that patients no longer need intravenous sedatives, narcotic analgesics, or general anesthesia. As a result of the widespread capillary constriction caused by the epinephrine in the anesthetic solution, there is minimal bleeding during and after surgery. This is a major improvement in the liposuction technique compared to the older methods that simply use general anesthesia.
    To conclude, Tumescent liposuction is a safe and effective procedure when performed in trained hands in a proper setting. Experience and training of surgeon, proper selection of cases, and proper technique in anaesthesia and aspiration are all important to get optimal results. It is important to keep in mind that, as in any cosmetic procedure including liposuction, a final safe and satisfactory result is far more important than quick results.
