What are the causes of fatigue after eating

insomnia

  • Reactive hypoglycaemia

After a meal, dense in carbohydrates, you may experience reactive hypoglycaemia, which leaves you feeling fatigued after eating and may also lead to irritability, light-headedness and headaches. This is caused by a spike in your insulin production. When your body finishes digesting, your levels dramatically drop, resulting in a sugar crash.

  • Tryptophan

This increases the production of serotonin, the neurotransmitter responsible for moods, sleep and regulating bowel movements. Foods high in tryptophan cause spikes in insulin leaving you drowsy after meals.

  • Alkaline tide

This occurs during the first two hours of digestion and elevates the blood’s pH level. The process produces an alkaline which is released into the plasma of the stomach and makes the blood from the stomach more alkaline.

  • Allocation of resources

The theory goes that oxygen and blood are allocated to the digestive system in the same way muscles are used when working out, but this theory is not scientifically backed, but it could explain the fatigue.

  • Certain conditions

Diabetes and Hypothyroidism can cause fatigue after eating. Diabetes reduces the absorption of glucose and Hypothyroidism makes the glands unable to produce sufficient thyroid hormones.

  • Quality of food

Consuming food will leave you tired and fatigued. In contrast, vitamin foods can boost energy levels.

  • Portions

Large portions of unhealthy foods can leave you sleepy. Reducing portion size and eating smaller meals frequently allowing your body to digest smaller portions, which will leave you feeling less tired.

Consuming food you are allergic too can lead to fatigue, as your body battles to rid itself of the allergen, expanding energy as your immune system protects your body. Check out our allergy nurse Marlene for more information.
