You may eat well, exercise, and feel in good shape, yet aging can still bring health problems.
Certain conditions become more common or severe as the body changes with time.
Flu

After age 65, the immune system weakens, making complications such as pneumonia, sepsis, and worsening of heart or lung disease more likely.
An annual flu shot is strongly recommended, and older adults should ask their doctor about the high-dose version for extra protection.

Weight gain

Aging reduces muscle mass, lowers activity levels, and slows calorie burn, which makes weight gain more likely.
Extra pounds increase the risk of heart disease, diabetes, and mobility issues. Even small lifestyle changes can help.
Exercise plans tailored to one’s health level are especially beneficial.
Sleep problems

Older adults need 7–9 hours of sleep, but aging alters circadian rhythms, causing earlier bedtimes and wake-ups.

Too little sleep after 50 can lead to memory issues, depression, pain, and a higher risk of nighttime falls.
Nutrition problems

The body absorbs nutrients less efficiently with age, often leading to deficiencies in vitamin B12, calcium, vitamin D, and vitamin B6.
A daily multivitamin may be enough, but high doses can be harmful. It’s important to consult a doctor, particularly when taking prescription medications.
Fragile bones

Osteoporosis makes bones weaker and more prone to fractures. Women over 50 are especially at risk.

A diet rich in fruits, vegetables, and calcium, combined with weight-bearing exercise and vitamin D supplementation, can help strengthen bones.
Avoiding smoking and limiting alcohol is also key.
Cancer

Age is the strongest risk factor for cancer, with half of all cases occurring in people over 65.
Healthy habits such as weight management, less red and processed meat, and regular exercise can lower risk.

Screening tests for breast, colon, skin, cervical, and prostate cancer are recommended after age 50.
Depression

Depression is not an inevitable part of aging, but symptoms often go unnoticed or are misattributed to age.
Chronic illness, loneliness, and dependence on home care can increase risk.
Treatment options include lifestyle changes, therapy, and medication. Staying socially connected can also have a strong protective effect.

Memory loss

Mild forgetfulness is normal with age, but serious problems such as forgetting directions or basic tasks may signal dementia or Alzheimer’s disease.
These conditions usually worsen over time and require medical attention.
Alcohol tolerance changes

With age, the body tolerates alcohol less, meaning effects like slowed reaction time appear faster and with smaller amounts.
It is important to share alcohol habits with a doctor, as they may affect treatment and medication safety.
Risk of falls

Reduced balance and weaker muscles make older adults more prone to falls, which can have serious consequences.
Strength and balance exercises, along with home adjustments, can reduce risks.
Multiple health conditions

As people age, it becomes more common to manage several chronic conditions at once.
This increases the complexity of treatment, especially when multiple medications are involved.
Regular checkups and communication with healthcare providers are essential.
