Reasons Why You Get Dizzy When You Quit Smoking

It is common for people to report the side effect of dizziness and lightheadedness when going through quitting smoking. This can be for various reasons, including nicotine overdoses (when trying nicotine replacement methods), hyperglycemia, anxiety, and dehydration. You can use methods to help minimize this side effect, especially if you can identify which of these factors is causing your dizziness. Read on to understand the different causes of dizziness while you quit smoking and why they occur.

Nicotine Overdoses

While trying to quit smoking, many use nicotine replacement methods such as patches or gum. These can be incredibly beneficial, but when overused, they can result in a nicotine overdose. Nicotine is a stimulant. This means that taking too much can overwhelm your system. Ensure that when you start using a nicotine replacement quitting method, you check how much nicotine is in each product and try to match the amount of nicotine to the amount you consumed when smoking. This will help prevent overdoses from happening, and therefore reduce your chances of experiencing dizziness whilst going through the process of quitting. It is also important to start slowly reducing the amount of nicotine you consume to reduce your addiction.

Hyperglycemia and Blood Sugar Instability

Hyperglycemia means raised blood sugar levels. When you are a smoker, your consumption of nicotine slows down your pancreas’ function – the organ that controls the release of insulin. This means that the release of insulin into your bloodstream does not properly match the release of sugar when you eat. As a result, the sugar stays in your bloodstream for longer than it should. This leads to a rise in your blood sugar levels. Your blood sugar levels end up being more unstable overall, resulting in some feelings of dizziness when you adjust your nicotine intake.


Quitting smoking can be an anxiety-inducing process. A common side effect of experiencing increased anxiety is lightheadedness or dizziness. You could be struggling with emotional regulation after using smoking as a coping mechanism, or you may simply be struggling with other side effects. To minimize the effects of anxiety, try methods such as breathing exercises or meditation sessions. These can help you to regulate your emotions better without having to rely on the help of cigarettes. If you are struggling significantly, seek the help of a healthcare professional for advice


When quitting smoking, it is not uncommon to experience dehydration. This occurs due to your body trying to cleanse itself – it will be adjusting to the absence of smoking and nicotine. Whilst quitting smoking, make sure that you drink plenty of water every day. This is vital to remain healthy and hydrated. It is also important to note that lightheadedness resulting from dehydration can be particularly severe when getting up quickly. Make sure to take your time with your movements when experiencing lightheadedness and dizziness to stay safe.

Overall, dizziness is normal to experience when quitting smoking. Try to identify the cause of your dizziness, and take care to look after your needs.
