7. Ammonia Breath
Kidney disease can also cause a metallic taste in the mouth or ammonia breath. This happens because poor kidney functioning leads to an increase in the level of urea in the blood. Urea is broken down to ammonia in the saliva, thus causing urine-like bad breath known as ammonia breath.
It can also cause an undesirable metallic taste in the mouth, which can make food taste different.
8. Nausea or Vomiting
Nausea, vomiting and poor appetite are very common gastrointestinal symptoms among people suffering from kidney disease. Nausea and vomiting most often occur when you get up in the morning.
As the kidneys are not able to filter harmful toxins out of the blood, it leads to an accumulation of excessive urea nitrogen in the blood stream. This stimulates the gastrointestinal mucosa and causes nausea and vomiting.
If you are still experiencing nausea and vomiting after taking medicines and necessary preventive measures, consult a doctor before the condition becomes worse.
