Eating before a blood test will cause your blood sugar levels to rise. That is why they are referred to as "fasting" blood tests, meaning you are not supposed to eat or drink anything but water before having them.

What is the effect of exercise on blood pressure levels?

Regular exercise has been shown to have a positive effect on blood pressure levels by helping to lower both systolic and diastolic blood pressure readings. This is because exercise strengthens the heart, improves blood circulation, and helps to maintain a healthy weight, all of which contribute to better blood pressure control.


Why do I crash after I eat?

Crashing after eating can happen due to a rapid rise and fall in blood sugar levels. When you eat, your body releases insulin to help regulate blood sugar. If you consume a lot of sugary or high-carb foods, your blood sugar can spike quickly, leading to a subsequent drop in energy levels, causing you to feel tired or sluggish. Eating balanced meals with protein, fiber, and healthy fats can help stabilize blood sugar levels and prevent crashes.


How does the body regulate blood glucose levels?

The body regulates blood glucose levels through a hormone called insulin, which is produced by the pancreas. When blood sugar levels rise after eating, insulin is released to help cells absorb glucose for energy or storage. Conversely, when blood sugar levels drop, another hormone called glucagon is released to signal the liver to release stored glucose into the bloodstream. This delicate balance helps maintain stable blood glucose levels.
