Smoking and blood sugar levels are interrelated

Type 2 Diabetes - Nicotine is the main culprit responsible for high blood sugar levels in smokers with diabetes.
Nicotine may also lead to insulin sensitivity and insulin resistance, as well as an increased risk of developing metabolic syndrome, type 2 diabetes and cardiovascular disease; thus nicotine impacts the body's glucose metabolism, leading to hyperglycaemia and hyperglycaemia associated with insulin resistance. Furthermore diabetes causes complications such as heart attackstroke, kidney failure, and nerve damage.

What is nicotine
Nicotine is a drug found naturally in tobacco, which is as addictive as heroin or cocaine. Over time, a person becomes physically dependent on and emotionally addicted to nicotine. This physical dependence causes unpleasant withdrawal symptoms when a person tries to quit.

Nicotine causes pleasant feelings and distracts the smoker from unpleasant feelings. This makes the smoker want to smoke again. 

When a person finishes a cigarette, the nicotine level in the body starts to drop, going lower and lower. The pleasant feelings wear off, and the smoker notices wanting a smoke. If smoking is postponed, the smoker may start to feel irritated and edgy.

Withdrawal symptoms may include following:

  • Dizziness (which may last 1 to 2 days after quitting – can be due to low sugar level)
  • Depression and feelings of frustration
  • Anxiety and irritability
  • Sleep disturbances having trouble falling asleep and staying asleep
  • Trouble concentrating – easily distracted
  • Boredom
  • Headaches
  • Increased appetite
  • Weight gain

Brain chemistry
A person finds it difficult to stop smoking because the nicotine they have been inhaling for many years has changed their brain chemistry to create powerful urges to smoke. 

The craving sends a rapid nicotine hit to the part of the brain that makes a person do things making a connection between the drug and the action, such as after a meal, having a drink, watching the television or a break after so many hours of work.
