Which diseases cannot pass the physical examination

Routine physical examinations often fail to screen for early asymptomatic malignant tumors, latent infectious diseases, some neurological disorders, genetic metabolic disorders, and mental and psychological disorders. It mainly includes early lung cancer, AIDS window period, early Alzheimer's disease, phenylketonuria, depression, etc.

1. Early lung cancer

Chest X-rays or low-dose CT scans may miss small nodules, and early lung cancer often does not have symptoms such as cough or chest pain. It is recommended that long-term smokers and individuals with a family history undergo tumor marker testing, and if necessary, undergo bronchoscopy or PET-CT examination.

2. AIDS window period

HIV antibody test has a 6-12 week window period, at which time the viral load is high but the test is false negative. If there is high-risk behavior, it is necessary to have a follow-up examination after the window period or directly undergo nucleic acid testing. During the acute phase, non-specific symptoms such as fever and rash may occur.

3. Early Alzheimer's disease

Routine brain CT/MRI is difficult to detect early brain atrophy, and cognitive function questionnaires are susceptible to subjective influence. Symptoms such as memory loss and orientation disorders often progress to the middle stage. APOE gene testing can assist in risk assessment.

4. Phenylketonuria

Newborn heel blood screening can detect this genetic metabolic disease, but adult physical examinations do not include this item. Untreated can lead to intellectual disabilities and epileptic seizures. It is necessary to control phenylalanine intake for life and avoid high protein foods such as meat and dairy products.

5. Depression

Physical examination centers have limited sensitivity in screening physical scales, and mild depression is easily overlooked. Persistent low mood and decreased interest for more than 2 weeks should be evaluated in a psychiatric department and differentiated from organic diseases such as thyroid dysfunction.

It is recommended to increase specialized examinations based on individual risk factors, such as gastrointestinal endoscopy screening for gastrointestinal tumors, HPV testing to prevent cervical cancer, and apolipoprotein E gene testing to assess the risk of Alzheimer's disease. Maintaining a healthy lifestyle such as regular exercise, balanced diet, and sufficient sleep can help reduce the probability of potential diseases. Seek medical attention promptly when warning symptoms such as unexplained weight loss and persistent pain occur.
