If the elderly person is sick, the age of the disease goes through stages of the disease, the nature of which is different from the nature of the disease. There are severe diseases such as pneumonia, or a fracture dislocated femur that requires hospitalization at this stage, and then after recovering from ill health, the elderly continue to fight the rest of his chronic diseases, such as depression, Alzheimer's, heart failure, or any other chronic disease, and this is another stage in the journey of the disease. It is even more complicated if the elderly reside alone, and there is no sponsor. There is an elderly person who has become bedridden and cannot rely on himself for his personal needs. This is a link to the rest of the other episodes. Based on the above, there must be a correlation between the health-care cycles between which the elderly move.

These episodes can be shortened to:

 1 - acute care ring, provided in hospital under the care of a doctor specializing in geriatric diseases.   2- Chronic care, provided in two places depending on the elderly's ability to move to the place of service. If he can move around, he will continue his health at geriatricclinics. If he cannot move, he will be cared for at home.
 3 -If he is bedridden and has a family, the best place to care for him is at home, provided that he is supported in a health care at home, to suit his condition, and who will benefit from the home health care system.
 4 - If there is no parents, in this case, it is necessary to find nursing homes, whose role is mainly based on the provision of nursing care, which provides the elderly with nutrition and personal care.

The philosophy of health care for the elderly is based on an understanding of the nature of this age group and the nature of the diseases to which they are exposed, which require preparation to confront an elderly person whose reserves of all organs of his body may be worn out.
It should be noted that the elderly are exposed to all the diseases to which the individual is exposed in youth, but with the very important and dangerous consideration that the same diseases may appear on the elderly quite differentfrom those in the younger ones, so a doctor specializing in the diseases of the elderly is required.

In addition, there are two things: first, there are diseases that occur only in the elderly, such as: dementia, sudden mixing of consciousness, incontinence, and falls. The other thing, which is the most important of all, is that the elderly are prone to very rapid functional deterioration, i.e. within a few days of succumbing to constant sleep, especially in the hospital, his muscles are weakening so rapidly that he cannot walk again and forever.
Therefore, there must be a specialist who understands all these dimensions, in order to be able to draw up an integrated treatment plan, with the aim of keeping the elderly at the highest possible level of independence, i.e. he can go to the bathroom himself and without help, at the very least.
