Heart attack: A heart attack is a medical emergency that occurs due to the blockage of blood flow to the heart due to blood clots. Due to this, the tissues lose oxygen and die. Symptoms include fatigue, light-headedness, and tightness/pain in the chest, arms, neck, or back.
Stroke: Stroke occurs when the blood supply to the brain is interrupted or reduced. Lack of blood supply and oxygen to the brain leads to damaged brain cells and tissues; this causes the death of brain cells within minutes, leading to stroke. Symptoms of stroke include difficulty speaking, paralysis on one side of the body, vision problems, severe headache, confusion, numbness, and loss of coordination or balance. Stroke requires immediate medical attention to prevent brain damage, long-term disability and death.
Aspirin-associated peptic ulcers: Aspirin may damage the gastric mucosa, leading to the formation of ulcers. Peptic ulcers are sores that develop on the lining of the stomach, oesophagus or small intestine due to erosion of the protective stomach lining. A gastric ulcer is an ulcer of the stomach lining, whereas a duodenal ulcer is an ulcer on the duodenal lining. Symptoms include nausea, changes in appetite, bloody or dark stools, unexplained weight loss, vomiting, and indigestion.
