Lipoid pneumonia pathogenicity is because of lipid aspiration. Common risk factors in the development of aspiration pneumonia include dysphagia, swallowing dysfunction, altered mental status, COPD, and hospitalization. Less common risk factors in the development of aspiration pneumonia include medications, esophageal motility disorders, vomiting, enteral feeding, oropharyngeal colonization, male sex, and smoking.

• Lipoid pneumonia major risk factor is vaping, E-cigarette smoking, occupational (fire eaters) , lipoid laxatives, aspiration pneumonia.
• Common risk factors in the development of aspiration pneumonia include dysphagia, swallowing dysfunction, altered mental status, COPD, and hospitalization.^[1][2][3]
• Less common risk factors in the development of aspiration pneumonia include medications, esophageal motility disorders, vomiting, enteral feeding, oropharyngeal colonization, male sex, and smoking.

• Common risk factors of developmentin lipoid pneumonia:^{[4][5][6][7][8][9][10][11][12]}
  • The aspiration or inhalation of fatty substances is a central causative factor for exogenous lipoid pneumonia.
  • Trivial habits such as use of oil based laxatives, lip balm, lip gloss and petroleum jelly.
  • Siphoning of various mineral oils (e.g., diesel) from containers.
  • Traditional folk remedies such as the use of oily nasal drops.
  • Forceful animal fat feeding, such as ‘ghee’, in children to establish regular bowel habits.
  • Trans nasal prescriptions of oil based drugs to treat cough and cold.
  • Iatrogenic complication following bronchography using the dye propyliodone.
