Biochemical and immunological parameters

Old age is a stage of life characterized by a series of physical and physiological changes in the body. As we age, it is essential to understand how biochemical and immunological parameters are affected by the aging process and how these changes can influence health and well-being at this stage of life.

In this session, we will explore in detail the biochemical and immunological parameters in the elderly.

Introduction to old age

The third age, also known as old age, is a stage of life that generally begins around age 65. As people age, their bodies undergo a number of physical and metabolic changes that can influence their health and quality of life. It is critical to understand these changes and how they affect biochemical and immunological parameters.

Changes in biochemical parameters

Basal metabolism: One of the most significant changes in old age is a decrease in basal metabolism. This means that the body burns fewer calories at rest, which can lead to weight gain if caloric intake is not adjusted. In addition, a slower metabolic rate can affect nutrient absorption.

Kidney function: Kidney function tends to decline with age. This can affect the body's ability to eliminate waste products and regulate fluid and electrolyte balance. Reduced kidney function can also influence how certain medications and nutrients are processed.

Lipid profiles: Blood lipid levels, such as cholesterol and triglycerides, can change with age. Elevated blood lipid levels are a risk factor for cardiovascular disease, which is more common in the elderly. Monitoring and control of these parameters are essential to maintain cardiovascular health.

Changes in immunological parameters

Immunosenescence: Immunosenescence is the aging process of the immune system. As we age, the immune system may become less efficient and less able to defend against infections. This can lead to increased susceptibility to infectious diseases.

Chronic inflammation: Chronic inflammation, or low-grade inflammation, is common in the elderly. This inflammation can contribute to the development of chronic diseases, such as heart disease and diabetes. Chronic inflammation can also influence the immune system's ability to function properly.

Response to vaccines: Response to vaccines may decrease with age. This means that older people may have reduced protection against vaccine-preventable diseases. It is important for older people to receive recommended vaccinations to maintain their health.

Strategies for maintaining health in later life

Diet and exercise: A balanced diet and regular physical activity are essential for maintaining a healthy metabolism and controlling biochemical parameters such as blood lipid levels. In addition, exercise can help maintain muscle strength and mobility.

Supplementation: In some cases, nutritional supplements may be necessary to ensure adequate intake of essential nutrients, especially in those who have difficulty absorbing nutrients from food.

Vaccination: Regular vaccination is crucial to prevent infectious diseases in the elderly. Consulting with a health professional about recommended vaccinations is essential.

Regular medical follow-up: Regular medical follow-up is essential to monitor biochemical and immunological parameters and detect health problems early. It also allows treatment and medical care to be adjusted as needed.
