Rob Kardashian is reportedly going to seek treatment for his depression and drug addiction. He had gone through a tough phase after his 100-pound weight gain.

According to the Centres for Disease Control (CDC), nearly one in ten Americans go through depression, it also states that nearly 70 million people in the country are obese. Studies have found a link between depression and obesity, but which one causes the other is still not confirmed, but researchers state that one feeds the other.

Kardashian too had gained a lot of weight in the past three years which had led to depression and anxiety. He had been struggling with depression since long and had been avoiding the media. In one episode of Keeping Up With The Kardashians, his mother Kris Jenner stated, "Everybody goes through stuff." She added that her son was struggling. Khloe Kardashian, his sister, admitted that he was always depressed and he never left the house.

A source told InTouch that the 27-year-old was looking at Bridges to Recovery, a California-based facility. The source also revealed that Rob was very keening on seeking treatment, "He's never said that before, so everyone thinks it's a good sign."

His sister Kourtney stated that Rob's serotonin levels had also fallen to low a level which is extremely bad. He was also doing drugs, a source reported. Weeks before Kim's wedding, he was reportedly smoking weed, watching movies and overeating. He even missed his sister's wedding because he felt depressed about his looks and had lost his self esteem.

Studies reveal that obese people have a 25 per cent more probability to experience mood disorders. Obesity is also seen to result in a poor self-image, low self-esteem, and social isolation this ultimately causes depression.

Rob has also started working out. Gunnar Peterson, renowned celebrity trainer, who has helped Khloe and Kim, is Rob's trainer as well. Rob is working out for long hours to lose weight, and Peterson stated that in a couple of weeks he will start feeling it and "will see major changes in six to eight weeks."
