During a Stern Show weight loss competition, Lange was the only contestant to actually gain weight. He has also been asked to appear on Celebrity Fit Club for each of four seasons, but has declined every time.
In May 2004, Las Vegas station KLAS-TV reported him dead. The story turned out to be a prank executed by Stern Show regular caller Captain Janks.
The website http://www.artielangedeathwatch.com was started to predict when Lange would die if he continues this lifestyle. Before discontinuing updates, the site projected that he would die at age 53. The site resulted in Artie getting turned down for special life insurance, when the company came across it.
Since quitting heroin, Lange has gained well over 100 lb (45 kg); on March 3, 2008, it was determined on The Howard Stern Show that he had reached 295 lb (134 kg).
Also in September 2007, Lange gave details of his experiences with sleep apnea. Lange claims that he has awoken in the middle of the night to use the bathroom and has fallen asleep while sitting on the toilet.
Artie was tested by John Hein for Type-2 diabetes on October 24 while on the Howard Stern show and his blood sugar was at 238. The next day on the show Artie stated his mother took him to see a doctor and was tested for diabetes. The tests came back negative and he stated his blood pressure was normal. The doctor, however, was very concerned with t
he speed that Lange has gained so much weight and suggested he go on a diet to save his heart. Since this incident, Artie has begun a moderate diet. Staff members have already commented that he looks less bloated.
On November 1, 2007, Lange revealed on-air that he had taken a tablet of Subutex and was feeling slightly high. Howard insisted it was because of his new diet. Less than an hour after feeling the effects of Subutex, Lange threw two objects, one of which being a CD case, in a fit of rage at cast member Sal the Stockbroker; the two were not on speaki
ng terms after a heated argument that they had the day before along with Richard Christy. Artie became frustrated once Sal and Richard attempted to amend the situation with an apology he found to be phony. Artie would soon afterwards apologize to Sal, admitting that he overreacted and crossed a line [he] never thought [he] would and would make
up with Sal and Richard one week later on November 8.
A picture on November 7, 2007 was revealed on air from the previous day when Artie was photographed holding a McDonalds bag and drink. Artie had called in sick the next day blaming his diet for his illness and the cast teased him anyway.
On November 14, 2007, Lange added an additional revelation that in his early 20s, he contracted chlamydia, a sexually transmitted disease. He said that it was likely from receiving oral sex from a prostitute at a bachelor party. His doctor felt it was possible that the prostitute reused a condom from another man who was infected with the STD. Lange
described having to receive a shot to fight the infection.
