Low blood sugar (Hypoglycaemia) can cause symptoms such as sweating, shaking, fast heartbeat, sudden hunger, dizziness, headache, blurred vision, irritability, weakness and difficulty concentrating. In more severe cases, a person may become confused, very drowsy, or may even faint or have seizures. If these symptoms appear, act quickly. Take fast-acting sugar such as a glass of sweet juice, sugar dissolved in water, or glucose tablets. Wait for about 15 minutes and check if symptoms improve. If still low or symptoms continue, repeat the sugar intake. Once you feel better, eat a small snack, such as bread or biscuits, to help maintain your blood sugar levels. If the person becomes unconscious, seek emergency medical help immediately and do not give anything by mouth. Always carry a quick source of sugar and avoid skipping meals, as regular eating helps prevent sudden drops in blood sugar.

When a glucometer displays ?low,? it usually means your blood sugar has fallen below a safe level. This can happen if you skip meals, eat very little, take diabetes medicine at the wrong time, exercise heavily without enough food, or have a long gap between meals. Low sugar may cause sweating, shaking, weakness, hunger, dizziness, blurred vision, fast heartbeat, or sudden confusion. If this happens, try to take a quick source of sugar immediately, such as glucose powder in water, fruit juice, regular soft drink, sugar candy, or glucose tablets if you are fully awake and able to swallow safely. After a short time, eating a proper meal or snack may help keep the sugar from dropping again. Frequent low sugar episodes should not be ignored because they may become risky, especially in older adults or people with heart disease. Keeping regular meal timings, monitoring sugar levels properly, and avoiding long fasting periods may help prevent sudden drops. Immediate medical attention may be needed if you become unconscious, develop seizures, have severe confusion, or are unable to eat or drink safely during an episode.
