The Ministry of Hajj and Umrah (MOHU) has outlined a list of chronic medical conditions that automatically disqualify applicants from performing Haj due to health and safety considerations. These include, but are not limited, to the following:

• Major organ failure (e.g. renal failure requiring dialysis, cardiac failure with symptoms on minimal exertion; chronic pulmonary disease requiring intermittent or continuous oxygen; advanced liver cirrhosis with hepatic failure).

• Severe neurological or psychiatric disorders that impair cognition or are accompanied by significant motor disabilities.

• Advanced age with associated dementia.

• Pregnancy during the final trimester, and high-risk pregnancies at any stage.

• Active communicable diseases that pose risks in mass gatherings (e.g. active pulmonary tuberculosis, viral haemorrhagic fevers).

• Active cancer patients undergoing chemotherapy or other forms of intensive immunosuppressive treatment.
