A variety of hangover cures have been developed over the years, but often with very little science behind them as people attempt to fight off the after effects of alcohol.

However, there are some hangover cures, some more surprising than others, which have a scientific basis and are relatively simple to apply, whether you have diabetes or not.


Feelings of nausea very often come with the feelings of a hangover, and a compound that accompanies this is acetaldehyde.

Acetaldehyde is formed in the body upon consumption of alcohol, which can also then have longer term effects on the health of the liver.

Acetaldehyde can be broken down, however, by an amino acid called cysteine, which is found in eggs.

Cysteine helps you feel better from a hangover by turning acetaldehyde into acetic acid, which has been used in folk medicine for centuries all over the world. This can then be converted into carbon dioxide and water.

Fruit (Kiwi fruit and bananas)

Generous amounts of potassium can be found in fruits such as bananas and kiwi fruits, an important nutrient which can help to refuel the body.

Alcohol is a diuretic substance that increases the discharge of urine, so following consumption trips to the toilet can become more common.

During these visits, the body’s store of salts, including potassium, are expelled from the body. This can result in tiredness, nausea and weakness.

Be careful to avoid excessive consumption of these fruits though, which can be high in carbohydrate and can therefore affect your blood sugar levels. Noting this before you eat fruit will enable you to select how much you can have.


Alcohol not only increases toilet trips, but it can also have dehydrating effects.

When drinking alcohol, an antidiuretic hormone called vassopressin is prevented from acting, which results in less water being reabsorbed by our kidneys.

As a result, the bladder takes in more water, which explains the increase in urination that comes with alcohol consumption.

Dehydration is therefore more likely because of the increased expelling of fluid, despite people thinking that by drinking more, the fluid will be reabsorbed once consumed.

Headaches can be a major symptom of dehydration, but water can rehydrate your body by flushing out any toxins left in the body.

Drink water before bed and first thing in the morning following alcohol consumption to limit these headaches and other hangover symptoms the next day.

Monitor blood sugar levels

Testing your blood sugar levels is important when drinking alcohol as adjusting any highs and lows can prevent contributions to the effects of a hangover.

Both high and low blood sugars can be influential in hangover symptoms, with high readings another factor that can lead to dehydration.

High blood glucose levels in people with type 1 diabetes can also result in raised ketone levels. While nausea can accompany this, a more dangerous element of high blood sugar levels is ketoacidosis, which can occur when the body starts running out of insulin.

It is worth testing your ketone levels if you have very high blood glucose levels, which could also occur if an injection has been missed at night time or in the morning.

Low blood sugars can occur overnight following alcohol consumption, with hypoglycemia often possible during sleep.

A low reading after drinking alcohol can lead to headaches and additional fatigue in the morning. Headaches may be attributed to alcohol and dehydration, but anyone on insulin or hypo-causing tablets can experience this as a symptom of low blood sugar. Consuming some carbohydrate before bed can prevent this.
