Disorder thinking is a characteristic feature of schizophrenia.

Diseases related to obesity
Obesity increases the risk of developing a large number of diseases including: Type 2 (adult-onset) diabetes; High blood pressure (hypertension); Stroke (cerebrovascular accident or CVA); Heart attack (myocardial infarction or MI); Heart failure (congestive heart failure); Cancer (certain forms such as cancer of the prostate and cancer of the colon and rectum); Gallstones and gall bladder disease (cholecystitis); Gout and gouty arthritis; Osteoarthritis (degenerative arthritis) of the knees, hips, and the lower back; Sleep apnea (failure to breath normally during sleep, lowering blood oxygen); Pickwickian syndrome (obesity, red face, underventilation, and drowsiness).

Diseases, inherited metabolic
Also called inborn errors of metabolism, these are heritable (genetic) disorders of biochemistry. Examples include albinism, cystinuria (a cause of kidney stones), phenylketonuria (PKU), and some forms of gout, sun sensitivity, and thyroid disease. These are only a very few of the hundreds of known inborn errors of metabolism. Advances in the diagnosis and treatment of inborn errors of metabolism have improved the outlook for many of these conditions so that early diagnosis, if possible in infancy, can be helpful. Many of the inborn errors of metabolism in young infants cause symptoms such as sluggishness (lethargy), poor feeding, apnea (stopping breathing) or tachypnea (fast breathing), and recurrent vomiting. Any infants, particularly full-term infants, with these findings should be seen and checked immediately by a doctor.

Diseases, rickettsial
The infectious diseases caused by the rickettsiae fall into 4 groups:(1) typhus: epidemic typhus, Brill-Zinsser disease, murine (endemic) typhus, and scrub typhus; (2) spotted fever-Rocky Mountain spotted fever, Eastern tick-borne rickettsioses, and rickettsialpox; (3) Q fever; and (4) trench fever

Disinsection
Spraying aircraft for insects, a procedure called disinsection.

Dislocation, congenital hip
The abnormal formation of the hip joint in which the ball at the top of the thighbone (the femoral head) is not stable within the socket (the acetabulum). The ligaments of the hip joint may also be loose and stretched. The degree of instability or looseness varies. A baby born with this condition may have the ball of the hip loosely in the socket (subluxed) or the ball of the hip may be completely dislocated at birth.
