Tammy Slaton's aggressive behavior in 1000-lb Sisters season 3 made her the series' unequivocal villain, and while viewers have plenty of theories to explain her antagonistic personality, some fans believe the reality star's breathing problems explain her inclination to bully her siblings. Viewers have noticed that with each new season, Tammy's health has decreased while her habit of starting fights with her family members has increased. Based on her extremely belligerent behavior in season 3 and her latest health crisis, here's why 1000-lb Sisters fans think Tammy's breathing trouble made her a villain.

Unfortunately, Tammy has done her best to ensure that she's at odds with her family members and support system in 1000-lb Sisters season 3. In the latest chapter of the Slaton clan's weight loss endeavor, Tammy fought her siblings on any effort they made to ease her health crisis. Tammy even threatened to get into a physical fight with her older sister, Amanda Halterman, in an especially tense altercation about Tammy's rude demeanor. On top of growing colder to her loved ones, Tammy also allowed her fitness to slip out of control in 1000-lb Sisters, which resulted in Tammy losing her ability to breathe. Fans theorize that Tammy's breathing trouble made her a villain in season 3.

Tammy and her sister, Amy Slaton-Halterman, decided to embark on weight loss journeys in 1000-lb Sisters season 1 because they knew that their health was in danger the longer they put off getting in shape. Unfortunately, Tammy failed to take her fitness mission as seriously as Amy has since season 1. While Amy's undergone bariatric surgery and given birth to her son, Tammy's health has continued to deteriorate as she's fallen further from her weight loss ambitions. In 1000-lb Sisters season 2, Tammy required an oxygen tube to breathe after contracting COVID-19. In season 3, Tammy's lungs continued to struggle, but this didn't deter the TV personality from vaping. Ultimately, Tammy suffered from oxygen poisoning and temporarily lost her ability to breathe altogether. Some viewers suspect that Tammy's villainous behavior in season 3 is the result of her breathing troubles.

Tammy's never been the kindest 1000-lb Sisters cast member, but she almost ended all of her relationships due to her aggressive attitude in season 3. Fans think Tammy's strained breathing contributed to her irritable behavior in 1000-lb Sisters. A Reddit user noted, "In those episodes, her lips look bluish around the rims. A lack of oxygen can make someone act totally off or exacerbate a crappy attitude." Fans noticed that Tammy's appearance indicates she had more breathing problems than she let on in season 3, which likely led to her nasty approach to her caring siblings. Another commenter believes that Tammy's outburst during the family's Smoky Mountains vacation was the result of her breathing issue, asserting, "[Tammy] was actually struggling to breathe at the mountain cabin." As much as fans disagree with the way she treated her siblings, fans think Tammy's breathing troubles made her a villain.

Even though 1000-lb Sisters fans regularly complain that Tammy Slaton needs to take more responsibility for her actions, some viewers think Tammy might've been nicer if she was able to breathe easily in season 3. From her reliance on an oxygen tube to her inexplicably cruel fights with her siblings, fans think Tammy's breathing made her a villain to rally against in season 3. After she gets out of rehab, fans can only hope Tammy will be able to take deep breaths and stay away from conflict in 1000-lb Sisters season 4.
