Aging & The Effects On The Body

Biological effects of Aging

There are many theories on aging and its causes. Some of the more prominent ones are:

DNA/Genetic Theory:

The DNA in our bodies contains a genetic blueprint, which we inherit from our parents and ancestors. This is a unique code, which determines a number of factors affecting the process of aging. This that attributes toward the damaging of our DNA during our lifetime, such as exposure to pollutants, toxins, radiation, our diet, and many other environmental and lifestyle factors, can affect the ability of our body to repair damage. This genetic damage can cause the production of abnormal proteins and sugar-protein complexes, which leads to defective cell repair, loss of cell elasticity, and other symptoms of the aging process.

Neuroendocrine Theory:

The pituitary gland and hypothalamus (a structure in the brain) regulate the release of key hormones to influence cell metabolism, protein synthesis, immune function, and the biochemical functioning of all bodily cells. The theory is that the hypothalamus over time loses its ability to regulate all these functions. The secretion of hormones gradually decreases over time, and this deterioration in the regulatory and hormone production process leads to aging.

Free Radical or Oxidation Theory:

This theory asserts that the unrepaired cumulative cell damage caused by free radicals, generated by normal metabolism, and contributed to by outside sources, is the cause for aging.

Cross-linking Theory:

During normal metabolism, sugars such as glucose or fructose and reactive compounds known as aldehydes and ketones may attach to free amino groups on proteins. This process is called glycation and the protein is then saddled with sugar molecules. This protein can then cross-link with other proteins to cause a bond between the two. They then may go on to react with free radicals to cause tissue damage through oxidation as they inhibit certain cellular processes. They can be mutagenic (cancer causing), and they can stimulate cells to produce even more damaging free radicals.

Immune Theory:

The immune system gradually gets less effective as we age. For instance, the thymus gland, which is responsible for the production of thymic lymphoid, or T cells, can decrease its function by up to 80% as we reach middle age. As we get older, the immune system is less able to produce the antibodies that the body needs to fight off infections and other assaults from the outside. There is also an increased tendency to produce antibodies against the body itself – the autoimmune response, which is responsible for a host of auto-immune diseases.

Whatever theory of aging ultimately proves to be correct, and ther are likely a number of factors which in combination will eventually be found to have a profound effect, it is unquestionably true that a significant number of problems faced by people over the age of sixty may also be attributable to nutritional deficiencies. Many elderly people have mal-absorption problems, in which the nutrients in food are not properly absorbed and their bodies do not assimilate nutrients as well as they once did.

Australia’s aged care industry provides home care, home support, retirement living and residential aged care, providing a choice of the level of care and well being for its elderly citizens.

The Australian aged care industry is constantly evolving to support aged carers and their patients, including:

  • In home care such as housework, shopping, cooking or social outings
  • Personal care such as dressing, eating, bathing or going to the toilet
  • Health care such as nursing, physiotherapy or medical assistance
  • Equipment such as walking frames
  • Home Modifications such as handrails and ramps
  • Residential care in a nursing home
  • Short-term (respite) care or after-hospital care

The aged care industry employs over 360,000 people, who care for more than 300,000 older Australians, ensuring the best possible, high-quality care available in the developed world.

Many students have relied on MLR Training Services for success!

Here are some of their stories.

I am currently working in the aged care industry, and decided to upskill to certificate IV through MLR Training. I found them very professional and supportive in helping me gain credit to apply for certificate IV. It was easily done and completed in no time. I highly recommend.
I completed my certificate 4 with MLR Training in the face to face class. The trainers were very helpful, and the content was presented in a way I could understand. They were always happy to answer questions I had and ensured I got my assessments done. They made the environment comfortable and enjoyable to come to class, they did roleplays and hands on activities which was helpful to learn. When I completed my 120 hours of placement, I was able to gain a position within the same facility. I would not have been able to complete this course without the help of the trainers and administration staff. I would recommend this company to anyone wanting a job in aged care.
I was working in the aged care industry with a certificate 3 and wanted to upgrade my skills. MLR Training offered an on-site certificate 4 upgrade. The trainers were very helpful and always answered any questions I had. The administration workers made enrolling very quick and easy. I now continue to work within the aged care industry and would recommend MLR Training to anyone wanting to work in this industry.
I was working in the aged care industry and wanted to upgrade my skills and qualifications by completing my Cert 4 in ageing support. I did face to face classes with MLR and found the trainers to be extremely supportive and motivating. The course content was presented in a way that was easy to understand and both trainers were there to assist whenever I needed help. I would highly recommend MLR to anyone wanting to pursue a career in aged care.
I completed my Certificate 4 upgrade from a certificate 3 with MLR Training and it was the most amazing experience. My trainer was extremely helpful and supportive. No question was a stupid question. Help was always available whenever I needed it. As I have been working in the Aged Care industry for 10 years so far, I will be using MLR to continue my up skilling in the future. Thank you MLR.
I completed my certificate 4 upgrade with MLR Training, and it was a great experience for myself. The trainers were very bubbly and made the process very enjoyable. They always answered my questions and helped when I needed it. I currently work in the aged care industry and with the help of MLR I was able to gain more knowledge around this area of work. I would recommend MLR Training.
I completed my certificate 4 with MLR Training and it was a wonderful experience. My trainers were supportive and encouraging throughout the course, they answered all questions I had and were there to help when needed. After the completion of the course I gained a position in community care and really enjoy my job. I would recommend MLR Training to anyone wanting to start a career in aged care.
I completed my certificate 4 with MLR training within their face to face class option. I was not sure what to expect when I started the course, but it was nothing short of an amazing experience. The trainers made the experience enjoyable always made the classroom an open and comfortable place to be. They delivered the content in a way everyone could understand catering for everyone’s learning needs. After the completion of my placement I gained a position at the facility I completed my hours. I would definitely recommend MLR Training to anyone looking at working within the aged care industry.
