Kurt Donald Cobain

Health history
Throughout most of his life, Cobain suffered from chronic bronchitis and intense physical pain due to an undiagnosed chronic stomach condition. His first drug experience was with marijuana in 1980, at age 13. He regularly used the drug during adulthood. Cobain also had a period of consuming "notable" amounts of LSD, as observed by Tracy Marander, and was "really into getting fucked up: drugs, acid, any kind of drug", observed Krist Novoselic; Cobain was also prone to alcoholism and solvent abuse. Cobain's cousin Beverly, a nurse, claimed Cobain was diagnosed with attention-deficit hyperactivity disorder as a child, and bipolar disorder as an adult. She also brought attention to the history of suicide, mental illness and alcoholism in the Cobain family, noting two of her uncles who had committed suicide with guns.
Cobain's stomach condition was emotionally debilitating to him, and he intermittently tried to find its cause, usually at the insistence of Love. None of the many doctors he consulted were able to pinpoint the specific cause. He suffered from an acute self-consciousness and developed a poor body image, due to his low body weight; which was primarily due to malnourishment caused by his stomach condition, poor diet (attested to by numerous doctors), or a combination of both.
