Quick answer: After 50, most heart and metabolic problems are quiet. High blood pressure, high cholesterol and prediabetes usually cause no symptoms, so they are found by measuring, not by feeling. This page is a map: what tends to change, the main questions worth asking, the symptoms that should not wait, what the evidence does and does not support, and where to find our detailed posts on each topic.
What changes after 50
Arteries gradually stiffen, which tends to push blood pressure up over the years. Body fat often shifts toward the middle, muscle mass tends to decline, and the body handles blood sugar less efficiently than it did earlier in life. Menopause is associated with changes in cholesterol and blood pressure in women, and men face rising risk earlier on average. None of this is destiny, but it is why routine measurements matter more in this decade than in the previous one. Several conditions in this category also overlap: blood pressure, blood sugar, cholesterol, kidney function and thyroid function each influence the others, which is why they are usually checked together.
The main questions in this category
High blood pressure
The 2017 ACC/AHA guideline calls a reading under 120/80 mm Hg normal, 120–129 with a diastolic under 80 elevated, and 130–139 systolic or 80–89 diastolic stage 1 hypertension. Stage 2 starts at 140/90. A reading above 180/120 is treated as a crisis: recheck after a few minutes, and seek urgent help if it stays that high, especially with chest pain, severe headache, shortness of breath, weakness or vision changes. A single reading in a clinic is not a diagnosis; confirmation usually involves repeat or home readings. Treatment is individual and often combines lifestyle changes and medicine.
Cholesterol
Cholesterol is measured with a blood test and has no symptoms. What counts as a concerning number depends on your overall risk (age, blood pressure, diabetes, smoking, family history), which is why clinicians look at the whole picture rather than one value. Cholesterol-lowering medicines have substantial trial evidence in people at higher risk; whether one is right for you is a conversation to have, not a number to self-assign.
Prediabetes and blood sugar
The CDC lists an A1C below 5.7% as normal, 5.7% to 6.4% as prediabetes and 6.5% or above as diabetes. Many people with prediabetes do not know they have it, and it is commonly rechecked every one to two years. Certain conditions, including severe anemia and kidney disease, can make A1C unreliable, so a clinician may use other tests.
Palpitations and dizziness
Fluttering, skipping or pounding beats are common and often harmless, but they can also signal rhythm problems such as atrial fibrillation, thyroid trouble or anemia. Feeling lightheaded on standing is frequently related to blood pressure changes or medicines. The pattern, duration and accompanying symptoms matter, and a clinician can decide whether a heart-rhythm recording is needed.
Kidney and thyroid health
Chronic kidney disease and an underactive thyroid are both common after 50, both can be silent early on, and both affect blood pressure, cholesterol and energy. They are found with simple blood and urine tests, which is a good reason to attend routine checkups even when you feel well.
Weight, muscle and protein
Losing weight gets harder with age partly because muscle mass declines and activity often drops. Newer weight-loss medicines raise their own questions about preserving muscle, and protein needs are a frequent topic. These are best decided with a clinician, particularly if you take other medicines.
Circulation in the legs
Varicose veins and leg swelling are common and usually benign, but sudden swelling in one leg, or pain with redness and warmth, can indicate a clot and needs prompt attention.
Symptoms that should not wait
Call emergency services (911 in the US) rather than waiting for an appointment if you have: chest pain, pressure or tightness, especially with shortness of breath, sweating, nausea or pain spreading to the arm, jaw or back; sudden face drooping, arm weakness or speech difficulty (stroke signs); sudden severe breathlessness; fainting; or a very high blood pressure reading together with any of those symptoms. Arrange a prompt visit for new palpitations that keep recurring, swelling in one leg, unexplained weight gain with ankle swelling, or breathlessness that is new for you. Women and older adults sometimes have less typical heart-attack symptoms, such as unusual fatigue or nausea, so a change from your normal is worth taking seriously.
What the evidence does and does not support
Daily aspirin. The US Preventive Services Task Force (2022) recommends against starting low-dose aspirin to prevent a first heart attack or stroke in adults 60 and older, because the bleeding risk outweighs the benefit on average; for ages 40–59 it describes starting as an individual decision for people with higher risk and low bleeding risk. This is about people without known heart disease and about starting, not stopping. If you already take aspirin, do not stop without asking whoever prescribed it.
Fish oil. In the VITAL trial, about 25,900 US adults aged 50 and older took 1 g a day of marine omega-3s or placebo for a median of 5.3 years. The main combined outcome of heart attack, stroke and cardiovascular death was not significantly reduced, though total heart attacks were lower. A companion analysis found no significant difference in atrial fibrillation at that dose. Prescription-strength products tested in specific high-risk groups are a separate question for a clinician.
Home blood pressure monitors and glucose sensors. A validated upper-arm home blood pressure monitor can give useful repeat readings to share with your clinician. Continuous glucose monitors are well established for people with diabetes; for people without diabetes the evidence that they improve outcomes is limited, and readings can cause needless worry.
Supplements for blood sugar or cholesterol. Some, such as berberine and CoQ10, have small or mixed trials and can interact with medicines. They are not substitutes for treatment you have been prescribed. See the supplements guide for how we approach evidence there.

Frequently asked questions
How often should I have my blood pressure and cholesterol checked after 50?
There is no single schedule that fits everyone. Many clinicians check blood pressure at every visit and cholesterol and blood sugar at intervals based on your results and risk factors. Ask your clinician how often is right for you, especially if a previous result was borderline.
Can I have high blood pressure or prediabetes without symptoms?
Yes. Both are usually silent, which is why measurement is the only reliable way to find them. Headaches or tiredness are not dependable signs.
Should I take a daily aspirin to protect my heart?
The US Preventive Services Task Force recommends against starting daily low-dose aspirin for primary prevention at 60 or older, because bleeding risk outweighs benefit on average. Do not start or stop aspirin without speaking to your clinician.
Does fish oil prevent heart attacks?
In the large VITAL trial of adults 50 and older, 1 g a day of marine omega-3s did not significantly reduce the main combined outcome of heart attack, stroke and cardiovascular death. Evidence for other products and populations differs, so ask your clinician.
Are heart palpitations always dangerous?
No. They are often harmless, but they can also reflect rhythm problems, thyroid disease or anemia. Seek urgent care if they come with chest pain, fainting or severe shortness of breath, and book a visit if they keep recurring.
