Effects of smoking

 

Tobacco smoke contains over 5,000 chemicals, including nicotine. Nicotine, when smoked, is highly addictive. People who smoke are addicted to the nicotine, but are harmed by the tar and other chemicals in tobacco.

Many of the chemicals can cause cancer. Others are poisonous, such as hydrogen cyanide, carbon monoxide and ammonia. When you smoke, these chemicals can not only damage your lungs, but also pass into your blood and spread through your body. Smoking can affect every part of the body - from your skin to your brain.

1.     Vision problems: 

      Smoking is associated with an increased risk of cataracts and age-related macular degeneration, which can lead to blindness.

2.     Lung cancer: 

     Smoking is the leading cause of lung cancer, which is one of the deadliest forms of cancer. Smokers are 15-30 times more likely to develop lung cancer than non-smokers..

3.     Respiratory diseases: 

     Smoking can cause chronic bronchitis and emphysema, two chronic respiratory diseases that can significantly reduce a person's quality of life. Smoking also worsens asthma symptoms and can lead to respiratory infections.

4.     Cardiovascular diseases: 

     Smoking increases the risk of heart attack, stroke, and peripheral vascular disease, which is a condition that affects the blood vessels outside the heart and brain.

5.     Reproductive and fertility issues:

     Smoking can lead to infertility in both men and women. It can also increase the risk of complications during pregnancy, such as ectopic pregnancy, miscarriage, and premature birth.

6.     Dental and oral health problems: 

     Smoking can cause bad breath, stained teeth, and gum disease. It can also increase the risk of oral cancer.

7.     Respiratory infections: 

      Smoking can weaken the immune system, making it harder for the body to fight off infections such as pneumonia bronchitis, and the flu.

Some common symptoms of kidney problems :  1    Loss of appetite Many patients with kidney disease complain about a loss of appetite, an odd taste in their mouth, or feeling full quickly. This is because the decline in kidney function can affect the substances that regulate your appetite. Additionally, built-up waste in the blood can cause a metallic taste in your mouth that can prevent you from enjoying normal foods.
