Are You Just Getting Older… or Could It Be Your Heart?
Written by Kristen Fellers, Nurse Prescriber.
Most of us expect our bodies to change as we get older.
We may notice less energy, slower recovery after exercise, or feeling more tired after a busy day. At some point, many people joke that every new ache or pain means they are “getting old.”
While ageing certainly changes the body, not every symptom should be blamed on birthdays and grey hairs.
Sometimes symptoms that seem like normal ageing can actually be signs of heart disease.
Heart problems become more common as we age. Many conditions develop slowly over months or years. The tricky part is that symptoms are often subtle at first. People adapt without realising it. They stop walking as far, avoid hills, or quietly give up activities they once enjoyed.
Below are some symptoms that deserve attention.
1. Shortness of Breath
Becoming puffed more easily is one of the most important warning signs.
If walking uphill, climbing stairs, carrying groceries, or mowing the lawn suddenly leaves you unusually breathless, it may be more than “being unfit.” Waking at night short of breath, or needing extra pillows to sleep comfortably, can also suggest heart problems.
Many people explain this away with comments like “I’m just getting older.” However, a noticeable change over a short period is worth investigating.
2. Reduced Fitness or Stamina
A gradual slowing down over decades is normal. A clear drop in exercise tolerance over months is less normal.
If you used to comfortably walk around the park or the lake, go tramping, or bike with friends but now struggle with activities that were previously easy, your heart may be under strain.
Sometimes people do not notice the decline themselves. Instead, family members notice they are stopping more often, avoiding activities, or lagging behind.
3. Chest Tightness, Pressure, or Indigestion
Heart-related chest symptoms are not always dramatic.
Some people experience pressure, heaviness, burning, or tightness rather than sharp pain. Others feel discomfort in the jaw, back, neck, or arms. Symptoms brought on by exertion and relieved with rest are particularly concerning.
Many heart attack warnings, and actual heart attacks, are initially mistaken for reflux or muscle strain.
4. Swollen Ankles or Legs
Mild swelling after a long flight or hot day can be normal. Persistent swelling, especially if it worsens over time, may indicate the heart is not pumping efficiently.
Shoes that are too tight to fasten or socks leaving deep marks can be early clues.
5. Dizziness, Blackouts, or Palpitations
Feeling faint, dizzy, or experiencing episodes of racing or irregular heartbeats should not be ignored. These symptoms can sometimes reflect abnormal heart rhythms or poor blood flow.
Seek urgent assessment if these symptoms occur alongside chest discomfort or breathlessness.
6. Severe or Persistent Fatigue
Feeling tired after a busy week is normal. Feeling exhausted by everyday tasks is not.
People with heart disease often describe a deep fatigue or “washed out” feeling. They may struggle with activities they previously managed easily.
Importantly, heart disease does not always cause pain. Conditions such as heart failure or valve disease may present mainly with fatigue and breathlessness.
Who Is More at Risk?
Smoking, diabetes, high blood pressure, high cholesterol, obesity, sleep apnoea, and family history all increase the risk of heart disease.
However, heart conditions also occur in active and otherwise healthy people. Not everyone with heart disease fits the stereotype.
The Good News
Not every symptom means something serious is wrong. Sometimes it really is just decreasing fitness, or the effects of ageing.
However, many people dismiss important symptoms for months or even years because they assume “this is just what getting older feels like.” They slowly adapt their lives around the problem instead of asking why it is happening.
Therefore it is important to pay attention to significant changes in your body, particularly changes in breathing, stamin and energy levels, or exercise tolerance.
Identifying heart problems can be as easy as an ECG (heart tracing) or blood test. And many heart conditions can be managed very effectively, especially when identified early. In some cases, treatment can improve symptoms dramatically and help people return to activities they thought they had simply “aged out of.”
Getting older is inevitable. However, becoming suddenly more breathless, exhausted, or limited is not necessarily a normal part of aging.
