Due to the overweight caused by OBESITY, the thorax and the abdomen are more
rigid and a bigger force is needed to displace the thoracic muscles for breathing
so the person gets easily tired and difficulty in breathing, even though in
short displacements, for what has to frequently interrupt the march and rest.
When the lung is more rigid for the mentioned previously, an increase of the lung sanguine volume takes place and small communications are formed in
those zones of the lungs where can be formed
accumulations of the elements of the blood and small thrombi present, unleashing
a pulmonary thrombosis.
In the patient who has OBESITY, a great variety of problems are presented from the
period before surgery since there is great difficulty to canalize the veins to
administer the solutions and the medicines.
During the anesthesia, problems
appear from the intubation (placement of a pipe in the trachea for best
ventilation). Equally the anesthesia by spinal route is more difficult to apply (spinal
anesthesia). The dose of anesthetic medications is very variable and it is very difficult to maintain an appropriate hydration.
During the surgery, the increase of fat in the fatty tissue, hinders the so much maneuvers of opening up as of closing the surgical incision and the control of the bleeding vessels is also hindered (hemostasia).
In the post surgery, the
mortality is increased in the patients that suffers OBESITY, by a decrease of the
concentration of oxygen in the arteries. There appear frequently pneumonias
(pulmonary infection), infections in the surgical wound and also is associated
to venous thromboembolism (inflammation of the veins) of low members.
