Smoking and Heart Attack Risk

Q: Q. Does smoking cause high blood sugar?

A. The high level of excretion of nicotine from cigarettes makes the body cells less responsive to insulin, which leads to an increment in sugar levels. Diabetic people exposed to high levels of nicotine need insulin to regulate their sugar levels.

Q: Q. Is the risk of heart attack reversible after quitting smoking?

A. Yes, the risk of heart attack is reduced after quitting smoking. The risk is reduced by half within one year of quitting and drops with time.

Q: Q. Is occasional smoking harmful to the heart?

A. Yes, even a light smoking habit increases heart attack risk. Smoking a few cigarettes has a measurable impact on the heart and increases the chance of heart disease.

Q: Q. Can secondhand smoke increase heart attack risk?

A. Yes, secondhand smoke is life-threatening. Inhaling the second smoke exposes non–smokers to similar toxic chemicals that active smokers inhale. This exposure will ruin the blood vessels and cause the buildup of plaque.

Frequently Asked Questions

Q. Why does the heartbeat increase while smoking?

A. Smoking people inhale carbon monoxide and carry less oxygen for red blood cells near the body. This means that the heart gets less oxygen to pump and speeds up the heart rate, and the body requires extra oxygen to function correctly. The heart recompenses, beating quickly to supply more oxygen.
