People with diabetes have a higher risk of cardiovascular disease, including stroke. The risk may be further increased when diabetes occurs alongside high blood pressure, unhealthy cholesterol levels, obesity, or smoking.
One challenge is that type 2 diabetes can develop gradually.
Some people experience increased thirst, frequent urination, unexplained fatigue, blurred vision, or slow-healing wounds. Others have few noticeable symptoms.
Routine testing can help identify elevated blood sugar before serious complications develop.
Two commonly used tests include:
Fasting blood glucose: Measures blood sugar after a period without eating.
HbA1c: Estimates average blood sugar levels over approximately the previous two to three months.
An HbA1c result can help healthcare professionals identify diabetes or prediabetes, although diagnosis and interpretation depend on clinical circumstances.
If you have diabetes, managing blood sugar is important, but it should not be the only priority.
Blood pressure, cholesterol, kidney health, physical activity, and smoking status also matter.
A comprehensive prevention plan is more effective than focusing on one measurement alone.
4. The Connection Between Heart Rhythm and Stroke
Not every stroke begins with a problem in the blood vessels of the brain.
Sometimes, the source of the problem is the heart.
One important condition is atrial fibrillation, often shortened to AFib.
Atrial fibrillation is an irregular heart rhythm in which the upper chambers of the heart beat in a disorganized manner.
When the heart does not contract effectively, blood may collect in certain areas, particularly in a small pouch of the left atrium. A blood clot can form there and potentially travel through the bloodstream to an artery in the brain.
If the clot blocks blood flow, an ischemic stroke can occur.
Some people with atrial fibrillation notice:
-
A racing or irregular heartbeat
-
Fluttering sensations in the chest
-
Shortness of breath
-
Dizziness
-
Unusual fatigue
However, others experience no symptoms at all.
This makes atrial fibrillation particularly important to recognize in middle-aged and older adults.
Not everyone needs continuous heart monitoring. A healthcare professional can determine whether a pulse assessment, electrocardiogram, or additional testing is appropriate based on symptoms and individual risk.
When atrial fibrillation is diagnosed, treatment may include medication to control heart rate or rhythm and, for many patients, anticoagulant medication to reduce the risk of blood clots.
These medications require professional guidance because they can increase bleeding risk.
Never start aspirin or an anticoagulant on your own to prevent a stroke. Aspirin is not appropriate for everyone, and it is not a substitute for anticoagulation when anticoagulation is indicated.
Why Women Should Not Ignore Stroke Symptoms
Stroke affects both men and women, but there are important differences in risk patterns and healthcare considerations.
Women may have additional risk factors associated with pregnancy, hormonal changes, and certain reproductive health conditions.
For example, pregnancy-related high blood pressure disorders, including preeclampsia, can increase cardiovascular risk later in life.
Women who have experienced preeclampsia, gestational diabetes, or pregnancy-related hypertension should mention this history during routine medical appointments.
Menopause is another stage when cardiovascular health deserves attention.
After menopause, changes in hormone levels may coincide with shifts in cholesterol, body composition, blood pressure, and metabolic health.
This does not mean that menopause directly causes a stroke. Rather, it is a useful point in life to reassess cardiovascular risk and discuss preventive care.
Women may also experience symptoms that are less commonly recognized as possible signs of stroke.
The classic warning signs remain essential:
-
Sudden facial drooping
-
Sudden weakness or numbness in an arm or leg
-
Sudden difficulty speaking or understanding speech
Other possible symptoms include sudden vision loss, severe dizziness, loss of balance, or an unexplained severe headache.
These symptoms should never be dismissed simply because someone is relatively young or has no known medical conditions.
The Difference Between a Stroke and a Transient Ischemic Attack
One of the most dangerous misconceptions about stroke is that symptoms are harmless if they disappear quickly.
A transient ischemic attack, or TIA, occurs when blood flow to part of the brain is temporarily disrupted.
Its symptoms can resemble those of a full stroke:
-
Temporary weakness on one side of the body
-
Brief difficulty speaking
-
Sudden vision problems
-
Temporary numbness
-
Sudden difficulty walking or maintaining balance
The symptoms may resolve within minutes or hours.
Because the person feels normal again, they may decide that medical attention is unnecessary.
That decision can be dangerous.
A TIA is an important warning that the brain may not be receiving adequate blood flow. It can indicate an increased risk of a future stroke.
It is not possible to reliably distinguish a TIA from a stroke based only on how long symptoms last. Even if symptoms disappear, urgent medical assessment is necessary.
Do not wait for symptoms to return.
Do not assume that sleeping, drinking water, or resting will solve the problem.
A healthcare team may need to investigate blood vessels, heart rhythm, blood pressure, cholesterol, and other potential causes.
Early evaluation can identify opportunities to reduce the risk of a more serious event.
What Should You Do If Someone Suddenly Shows Signs of a Stroke?
Knowing what to do during a stroke emergency may save a life.
The first few minutes can make a significant difference because some treatments are time-sensitive.
Remember the FAST warning system:
F β Face
Ask the person to smile. Does one side of the face droop?
A β Arms
Ask them to raise both arms. Does one arm drift downward or appear weak?
S β Speech
Ask them to repeat a simple sentence. Is their speech slurred, confused, or difficult to understand?
T β Time
Call emergency services immediately.
In Vietnam, call 115 for emergency medical assistance.
Do not drive the person to the hospital yourself if an ambulance is available. Emergency medical personnel can begin assessment and coordinate appropriate care.
There are several other important steps:
Note the Time Symptoms Began
If possible, record the exact time the person was last known to be well.
This information can help doctors determine which treatments may be appropriate.
If the person wakes up with symptoms, note the time they were last seen without symptoms before going to sleep.
Keep the Person Safe
Help them sit or lie in a safe position.
If they are conscious, reassure them and avoid unnecessary movement.
If they become unconscious but are breathing normally, follow emergency dispatcher instructions about positioning and monitoring their breathing.
If they are not breathing normally, begin CPR if you are trained and follow the dispatcher's instructions.
Do Not Give Food or Water
A stroke can affect swallowing.
Giving food, water, or oral medication may cause choking or aspiration if the person cannot swallow safely.
Wait for medical professionals to assess them.
Do Not Give Aspirin
Not every stroke is caused by a blood clot.
Some strokes occur because a blood vessel ruptures and bleeding develops inside or around the brain.
