Fatigue during pregnancy


  • In the early stage of pregnancy , the body produces a greater amount of a hormone called  progesterone .
    This hormone is responsible for fatigue and drowsiness.
  • The body begins to produce more blood and the consequence is an overwork of the heart and other organs.
  • In addition, it increases the metabolic rate and the body needs more energy to perform other tasks.

Causes of fatigue after ingestion of sugars

Increased Metabolism
In most situations, fatigue after eating sugars, pasta and sweets passes spontaneously after some time.
In fact, a lot of sugar:

  • It gives a feeling of more energy to the body,
  • Increases the body’s metabolism rate.

However, you may feel tired and drowsy right after you have burned the sugars.


  • Once a person consumes foods rich in sugars, blood glucose levels increase .
    This stimulates the pancreas to produce too much insulin .
  • A high amount of insulin causes many amino acids to enter cells except tryptophan .
  • If tryptophan has a higher blood concentration compared to other amino acids, it can more easily reach the central nervous system.
  • When tryptophan reaches the brain, it stimulates the production of a chemical called serotonin .
  • Serotonin is a neurotransmitter that regulates the sleep-wake cycle.
    This substance induces the feeling of tiredness  after eating sweets.

Pre-diabetes, diabetes and infections

  • One reason to be tired is pre-diabetes (carbohydrate intolerance).
    At this stage, blood sugar is higher than normal, but it is not enough to be considered type 2 diabetes .
  • The most likely cause of the feeling of fatigue after eating starch, sugars and carbohydrates may be the chance to develop diabetes .
  • A mild  allergy or infection (eg, candida or mononucleosis) could be the cause of fatigue.
