The warning signs of a stroke are not always obvious and can be easily mistaken or overlooked. However, some cases present noticeable early signs.

Unusual headaches. Not all headaches are related to stress, lack of sleep, or dehydration. A sudden and severe headache, especially if it feels different than usual, may signal a blood clot forming in the brain or increased pressure within the brain. This is especially concerning when accompanied by nausea or visual disturbances. These symptoms are often confused with migraines or stress-induced headaches. Besides regular exercise and a healthy diet, maintaining healthy blood sugar levels can also reduce the risk of blood clot formation.

Persistent hiccups with no apparent cause. Prolonged hiccups can sometimes be a sign of an impending stroke. This occurs when a stroke affects the medulla oblongata, the area of the brain that controls breathing and swallowing. While hiccups usually seem harmless, persistent hiccups lasting for hours or days without subsiding may indicate a more serious issue than a digestive problem. If unusual hiccups are accompanied by other symptoms like weakness or difficulty speaking, seek medical attention promptly.

Chest pain. This type of chest pain is not the crushing sensation associated with a heart attack. It's often mistaken for heartburn or indigestion. In some cases, it's related to reduced oxygen supply due to a blood clot in the brain's blood vessels. Unexplained chest pain should not be ignored, especially if it's a new symptom or doesn't subside. Cardiovascular and cerebrovascular health are closely linked; problems with one can affect the other.

Unexplained nausea during stress. Stress releases hormones like cortisol and adrenaline, which cause blood vessels to constrict. This can increase the risk of blood clots in people with pre-existing blood sugar imbalances. In this case, nausea isn't caused by food poisoning or a virus, but by the brain reacting to sudden internal pressure. People experiencing nausea rarely consider stroke as a potential cause, leading them to dismiss the symptom. Managing blood sugar levels by limiting sugar and starch intake can mitigate this risk. Individuals experiencing recurrent nausea during stress should consult a doctor, especially if accompanied by headaches or blurred vision.
