Because of the special nature of the old people’s physiology and pathology, the old people have their own special characteristics, including the following:
(1) at the same time, a variety of diseases
An old man with a variety of diseases at the same time. According to statistics, the elderly average at the same time with 4 to 6 kinds of diseases or more, such as an old man can also suffer from hypertension, coronary heart disease, hyperlipidemia and carotid push disease, mild cataract, lumbar muscle strain etc.. Although these diseases exist at the same time in the human body, but there is always a priority, there must be a 1 ~ 2 kinds of disease, the harm of, Yun to the risk of fatal.
2) disease complications
When complications when suffering from a particular disease, complicated byother illnesses on the basis of the disease. Due to the decrease of immunefunction in the elderly, poor resistance to external microorganisms andother exciting combat capability is weak, the prevalence in the elderly thanthe young are more susceptible to complications. For example old stroke,coma, after surgery or fracture are complicated by pneumonia.
(3) water and electrolyte disturbance
Normally the body needs a certain amount of water and essentialelectrolytes, such as potassium, sodium, and other, to meet metabolic needsand balance. Due to the intracellular fluid of the body of the elderlyreduces cell degeneration, organ atrophy if fever or vomiting, diarrhea,very prone to water and electrolyte disturbances.
(4) symptoms are not typical, not obvious
The elderly due to reduced body morphology and function, reaction of weakened, sensitive to the reaction of pain and disease in children and young people does not like. As in adolescence, when the high fever reaction in the elderly due to decreased reaction performance for low fever or fever, and if the elderly patients with my infarction, rarely in the middle-aged people with severe chest pain, but almost no pain or only show a slight sense of chest tightness. Therefore, the elderly are often not clearly explain their pain and discomfort, or vague expression.
(5) the occurrence of a mental disorder or mental disorder
Due to the elderly patients with atherosclerosis, insufficient blood supply to the brain, when infection, fever, dehydration, arrhythmia, etc., prone to lethargy, delirium, speak nonsense, delirious to coma and other symptoms, which is due to cerebral hypoxia. Some diseases may be the main manifestation of sudden coma.
(6) the onset of the disease is fast and prone to systemic failure.
The old people’s internal organs reserve function is low, once the illness, the disease is easy to deteriorate rapidly. This is due to the original state of the balance of some organs and functions of rapid failure and involves multiple organ damage.
(7) after the illness, recovery is slow and poor
Due to the low metabolic rate of the elderly, the function of tissue and organ regeneration ability is poor, so, after the illness often not easy to recover, or to recover slowly, the base to many diseases also left sequelae, often need to take rehabilitation measures.
(8) over reliance on drugs
Old people have a disease, which is an inertial reaction. The use of old people is a very complicated problem. Improper use of drugs, such as a doctor for a long time frequently to the patient to use a certain drug, the formation of the patient’s tolerance to a drug, drug misuse for the patient’s own reasons for the patient often not to the patient’s condition to use excessive drugs, resulting in drug resistance, drug abuse. Whether drug abuse, or drug abuse, can cause drug dependence.
(9) a greater response to the drug
Elderly patients, such as excessive or improper dosage, with the elderly themselves to the drug reaction, it is easy to drug toxicity reaction, and even because of drug reactions and increase the disease, or to make health threatened.
