Glossary for Nasal congestion

Medical terms related to Nasal congestion or mentioned in this section include:

  • Acute nasal congestion: Acute nasal congestion refers to sudden blockage of the nasal passages (stuffy nose) due to excessive production of mucus.
  • Acute rhinitis: An acute condition which affects the nasal mucous caused by inflammation
  • Acute sinusitis: An acute inflammation of the sinuses

  • Aromatic amino acid decarboxylase deficiency: A rare inborn error of metabolism involving the deficiency of an enzyme (aromatic L-amino acid decarboxylase) needed to process aromatic amino acids. This results in a deficiency of neurotransmitters such as dopamine and serotonin. The condition manifests as movement and neurological problems.
