Elderly physical and physiological changes and nutrient requirementsT. Tamilselvan
Physical and physiological changes occur as part of the aging process. Nutritional requirements also change in older adults. Adequate nutrition is important for preventing and managing common health issues in aging. Key nutrients that influence aging include protein, vitamins, and minerals. Maintaining sufficient intake of these nutrients can help support physical and cognitive functioning in the elderly.
The document discusses several topics related to aging:
1) Common theories for why aging occurs include programmed cell death and accumulation of damage over time.
2) The Free Radical Theory of Aging proposes that aging results from oxidative damage caused by reactive oxygen species. Antioxidants help protect against this damage.
3) Immortality is an intriguing concept but could have serious societal consequences like overpopulation and ethical issues in determining who lives forever.
4) Gender plays a role in aging as women on average live longer than men but face greater disadvantages from social and health inequities over their lifetime.
This document summarizes stem cell anti-aging therapy and rejuvenation. It discusses how aging occurs due to a decrease in stem cells over time, and how increasing stem cell reserves can help rejuvenate the body's systems and tissues. The document proposes a stem cell therapy program using fetal stem cells ("Golden Vial") to restore youthfulness by replenishing 240 types of stem cells to renew all functional systems of the body. It also discusses quantitative measures of biological age and frailty to objectively evaluate the effects of anti-aging treatments.
The document discusses several topics related to late adulthood and aging, including ageism, gerontology, changes in sensory abilities and physical appearance, theories of aging like wear and tear and genetic adaptation, and centenarians who live to be 100 or older. Some key points are that ageism is prejudiced based on age, gerontology studies aging, the brain and muscles change with age, and cellular aging and telomeres may limit lifespan while centenarians attribute long life to diet, attitude and lifestyle factors.
The document discusses sexually transmitted infections (STIs), which are passed primarily through sexual contact. Some STIs cause no symptoms but can still be transmitted to partners. Untreated STIs can lead to serious health problems. Those most at risk are those who have unprotected sex, multiple partners, or partners who use intravenous drugs. STIs are caused by microbes that thrive in warm, moist areas of the body. They are transmitted through sexual acts but some can also spread through blood or from mother to child. Common STIs in the US include chlamydia, gonorrhea, syphilis, herpes, AIDS, hepatitis, genital warts, and trichomoniasis.
The document discusses several theories related to aging and the aging process:
1. The programmed senescence theory states that aging and death are genetically programmed and hormones act as a biological clock controlling the pace of aging.
2. The wear-and-tear theory suggests that aging is caused by damage to cells and body systems over time from factors like radiation, toxins, and general "wear and tear" on the body.
3. Elizabeth Kübler-Ross' stage theory of death and dying proposes five stages - denial, anger, bargaining, depression, and acceptance - that terminal patients may progress through when coming to terms with their mortality.
The document discusses aging from biological, psychological, social, and cognitive perspectives. It defines aging as the progressive physiological changes in an organism that lead to a decline in functions and ability to adapt. Biologically, aging is associated with deterioration of organs and systems. Psychologically, aging involves changes in mental functioning and personality. Socially, aging impacts roles and relationships. Cognitively, aging causes declines in reasoning, memory, and processing speed. Theories of aging include the effects of wear and tear, tissue aging, disease processes, activity levels, stress, radiation exposure, nutrition, and lifestyle factors.
The document discusses how aging is not solely determined by genetics or the passage of time, but rather is influenced by lifestyle choices and environmental factors that can accelerate or decelerate the aging process. While lifespans have increased, quality of life in older years is not assured without steps to promote health. Factors discussed as impacting aging include inactivity, chemical pollution from medications, neurological stress from poor posture or injuries, and vertebral subluxations which can interfere with the nervous system. Maintaining activity, avoiding excessive medications, and addressing spinal issues can help support healthy aging.

The aging process causes changes in cells and organs over time through a combination of genetic and environmental factors. As people age, cells divide more slowly, immune function declines, and regulation of cell death is disrupted. Physically, aging is associated with loss of height, weight gain until late adulthood, increased body fat, and slower reaction times. While some organ decline is normal, lifestyle factors influence diseases like heart disease and cataracts. The aging process varies between individuals.
The aging process causes changes in both individual cells and organ systems over time through a combination of genetic and environmental factors. As we age, cells multiply more slowly, immune function decreases, and the process of cell death is disrupted. Bodily changes include loss of height from spinal compression, increased body fat and weight until mid-life, and altered drug processing. While some organ function declines gradually, normal aging itself is generally benign, though disease risks increase and individual aging rates vary.

Aging is the process of becoming older over time due to the accumulation of damage and wear and tear on the body. It occurs at the cellular level through the entire lifespan and involves physical, psychological, and social changes. The biological basis of aging includes both programmed factors regulated by gene expression and damage-related factors from internal and environmental assaults. Some ways to potentially slow aging include eating a healthy diet, not smoking, exercising regularly, maintaining social relationships, and getting sufficient sleep.
This document discusses aging and various theories related to it. It addresses what aging is, various theories that attempt to explain the aging process (such as programmed aging theory and genetic aging theory), signs of successful aging, life extension sciences, and strategies to potentially slow aging or extend life. The document provides a broad overview of topics relating to the biological, psychological, and social aspects of aging.
Aging can be defined in several ways:
1) As the time-related deterioration of physiological functions necessary for survival and fertility that affects all individuals of a species over time.
2) As a multidimensional process of physical, psychological, and social changes that occurs as humans get older.
3) As a progressive functional decline or decrease in viability that increases susceptibility to death and disease as intrinsic age-related changes accumulate over time.
Unit vi ageing process and physiological changes m.sc ii yrsanjalatchi
Normal ageing is characterised by a decrease in bone and muscle mass and an increase in adiposity . A decline in muscle mass and a reduction in muscle strength lead to risk of fractures, frailty, reduction in the quality of life and loss of independence [45]. These changes in musculoskeletal system reflect the ageing process as well as consequences of a reduced physical activity. The muscle wasting in frail older persons is termed ‘sarcopaenia’. This disorder leads to a higher incidence of falls and fractures and a functional decline. Functional sarcopaenia or age-related musculoskeletal changes affect 7% of elderly above the age of 70 years, and the rate of deterioration increases with time, affecting over 20% of the elderly by the age of 80 Strength declines at 1.5% per year, and this accelerates to as much as 3% per year after 60 years of age . These rates were considered high in sedentary individuals and twice as high in men as compared with those in women . However, studies show that on an average, men have larger amounts of muscle mass and a shorter survival than women. This makes sarcopaenia potentially a greater public health concern among women than among men
Late adulthood brings physical and cognitive changes. Life expectancy in the US is 75 years for women and 85 for men, though maximum lifespan is around 115 years. Physical changes include declines in vision, bone density, and sexual functioning. Sleep issues like apnea become more common. Chronic conditions like arthritis, heart disease, cancer and strokes are leading causes of death. Cognitive changes involve some memory loss and increased risk of dementia or Alzheimer's disease. However, older adults are thought to possess wisdom from considering life's problems in broader context of past experiences.
Aging is a natural phenomenon. it is the law of nature
this slide is about the various factors which independently or in combinations contribute to aging in humans
Ageing is a natural process that involves physical, psychological, and social changes over time in humans. While some abilities decline with age, such as reaction time, other abilities can grow, like knowledge and wisdom. Research shows that development and growth are still possible even late in life. Population ageing is occurring globally as life expectancy increases and birth rates decrease. Successful ageing involves maintaining good physical and cognitive health and an active lifestyle. The causes of ageing include a decline in immunity, cells, strength, and adaptation over time. Common physical, mental, emotional, social, and economic changes that occur with ageing are also described.

Caffeine; Does it really work for weight loss!.pdfaditi agarwal
Caffeine is a stimulant found in coffee, tea, and other beverages that increases alertness. It can promote weight loss by increasing metabolism, promoting fat burning, and suppressing appetite. The amount of caffeine needed depends on a person's BMI, with 200-400 mg recommended daily for most adults. Black coffee is one of the most effective sources for weight loss when consumed before meals without added sugar or cream. The best time to drink coffee for weight loss is in the morning before breakfast.
A Detailed Guide to the Atkins Diet.pdfaditi agarwal
The document provides an in-depth overview of the Atkins diet, including its phases and guidelines. It was created by Dr. Robert Atkins and focuses on low-carb, high-protein eating. The diet works by reducing insulin levels and forcing the body to burn fat instead of carbs. It allows meat, eggs, cheese and most vegetables but restricts fruit, grains and sugars. While effective for short-term weight loss, it is too restrictive long-term and may lack nutrients. The document also discusses pros, cons and differences between Atkins and keto diets.
Pyruvate for weight loss – Does it work!.pdfaditi agarwal
Pyruvate is a molecule produced during glucose breakdown that plays an important role in energy production. It can enter the mitochondria where it is further broken down and converted to acetyl-CoA to be used in the Krebs cycle. Supplementing with pyruvate may help with weight loss by increasing metabolism and fat burning, though more research is needed. Pyruvate supplements are generally well-tolerated but can cause side effects like diarrhea or nausea in some individuals.

2. While many people search for the
proverbial fountain of youth, you may be
wondering why, do we age in the first
place? For centuries, scientists,
philosophers, and even laypeople have
been debating the reasons behind aging. Is
it simply wear and tear? Is it programmed
into our cells? Are we just victims of bad
luck?
Well, not quite. Animals age, plants age,
and even rocks age. So, we know that it’s
not just a human condition. But why? Why
do we grow old? Why do our bodies age?
Why do we have to age? They are all “age”
old questions, aren’t they?
Bad puns aside, there are a few theories as
to why we age. And, while scientists are still
trying to figure out the answer to all of the
above questions and more, the last few
3. years have seen some pretty significant
breakthroughs in the field of aging
research.
So, let’s take a look at some of the most
popular theories on why we age and
explore the science behind each one. We’ll
also dive into some of the latest research on
aging and longevity, with just five of the
most significant breakthroughs happening
in our world today.
If you’ve ever wondered why we age, and if
there are any plans to do anything about it,
this article is for you.
What is Aging?
First things first, let’s define aging.
When most people think of aging, they
think of the physical changes that come
4. with getting older. You know, wrinkles, grey
hair, achy joints... that sort of thing. But
aging isn’t just about how our bodies look
on the outside; it’s also about how our
bodies function on the inside.
For example, as we age:
Our cells divide more slowly,
We produce less collagen and elastin
(which keeps our skin looking young and
plump),
Our hair follicles shrink (which is why our
hair gets thinner and greyer),
And our muscles atrophy (which is why we
get weaker).
5. Though it’s not just our physical
appearance and strength that change as
we age, our mental faculties also start to
decline. As a result, we have a more
challenging time learning new things, our
memories aren’t as sharp, and we become
more forgetful. We also become more
susceptible to age-related diseases like
Alzheimer’s, Parkinson’s, heart disease, and
cancer.
So, when we talk about aging, we’re talking
about the gradual deterioration of our
physical and mental abilities. But, of course,
it’s important to note that there are also a
lot of individual factors that contribute to
how quickly we age. For example, our
lifestyle choices, diet, environment, and
6. even our genes all influence how fast (or
slow) we age.
That said, there are some commonalities
when it comes to aging. And understanding
these commonalities is key to
understanding why we age in the first
place. So, let’s take a look at some of the
most popular theories on aging.
Why Do We Age? - Two Primary Categories
The most popular theories on the science of
aging can be divided into two main
categories: programmed aging and
damage-related aging. Let’s take a look at
each one in turn.
7. Programmed Aging
The first theory on our list is programmed
aging. Programmed aging posits that we
age because our cells are programmed to
do so. In other words, aging is written into
our DNA.
This theory has a lot of evidence to support
it. For example, studies have shown that the
length of telomeres (the protective caps on
the ends of chromosomes) predicts lifespan
in a variety of species. In humans, shorter
telomeres have been linked to a higher risk
of age-related diseases like heart disease,
stroke, and cancer.
Damage-Related Aging
The second theory on our list is damage-
related aging. This theory posits that we
age because our cells accumulate too much
8. damage over time. This damage can come
from various sources, including oxidative
stress, inflammation, and glycation (the
buildup of sugar molecules on proteins).
Damage-related aging also has a lot of
evidence to support it. For example, studies
have shown that oxidative stress increases
with age in an assortment of species. In
humans, higher levels of oxidative stress
have been linked to a higher risk of age-
related diseases such as Alzheimer’s
disease, Parkinson’s disease, and diabetes.
