What helps

Dressing in layers, even indoors
Avoiding extreme temperatures
Staying well hydrated

3. Digestive changes that affect almost everyone

The digestive system also undergoes changes.
After 70, the stomach produces less acid, the intestines move more slowly, and the absorption of certain nutrients decreases.

This can lead to:

Feeling full quickly
Constipation
Deficiencies in vitamin B12, iron, or calcium

Many people assume it’s “normal to feel heavy,” but in reality, it’s a digestive system that now requires more care.

What helps

Eating smaller portions
Increasing natural fiber intake
Drinking water throughout the day

4. Balance weakens, but it can be trained

One of the most dangerous changes after 70 is the loss of balance.
This is not only due to muscles, but also to changes in the inner ear, vision, and the brain’s reaction speed.

The good news is that simple balance exercises can reduce the risk of falls by up to 45%.

Some examples:

Standing on one foot while holding onto a chair
Walking in a straight line, placing one foot in front of the other
Gentle tai chi or slow, controlled movements
