Thus, in cases of headache, there are assuredly many which are produced by superabundance of fat, because they commenced when that superabundance began to appear, and ceased on its being diminished. Frequent headache, becoming periodic, is constantly met with in fat people. Nothing is more common among such persons than dizziness. In these cases, are not the blood-vessels oppressed with fat interfering with a free circulation of the blood, and is not fat therefore the cause of all these troubles? But it may be said that the blood produces these affections, since, after loss of blood, the patients are relieved. I do not agree with this, and I say that the blood is not in such cases the cause of these ailments; because fat people, both men and women, have no more blood than thin persons: I maintain that they have even less. It is granted that loss of blood in cases of headache, vertigo, alleviate and even cure these affections; but only for a time; for eight days, or a month or two at the most, and then gradually reappear, and bleeding is again required. This amelioration, these momentary cures, produced by blood-letting, are to be explained in such cases by saying that the quantity of blood, although not so great in fat as in thin people, is impeded in its circulation, and that loss of blood, by still further diminishing the quantity, facilitates for a while its passage through the blood-vessels. This method is consequently only palliative; it does not attack the root of the evil. Bleeding takes away blood which is troublesome only in consequence of the excess of fat; for every physician is aware that repeated bleedings tend to the development of fat in an extraordinary degree. Fat people insist upon being bled at more frequently recurring periods, because their corpulence continues to increase, and headaches and dizziness become more frequent. The seemingly useful remedy increases the cause of the trouble. Notwithstanding the temporary relief, and apparent cure, corpulence finally produces such a disturbance of the brain, or of some other vital organ, as suddenly to produce death in the course of an hour or two, with every appearance of excess of health. Usually an attack of serous or sanguineous apoplexy is the cause of death in persons labouring under excessive corpulence.
