Teddi Mellencamp is not hiding the hard parts of her cancer battle.
After the Real Housewives of Beverly Hills alum shared that her cancer had progressed to stage four in February, she gave fans insight into why she ended her immunotherapy treatment due to it leaving her feeling worse.
“I hadn’t been feeling good for about a month,” Teddi shared on the July 23 episode of her and Tamra Judge’s Two Ts in a Pod podcast. “Which was kind of shocking to me, and I think mentally did a lot to me. I was like, ‘What do you mean? I felt so good right after the surgeries and then when I was having radiation and immunotherapy I was feeling good so why do I feel like I can barely do this right now? Why do I feel like I can barely open my eyes and keep my words straight?’”
She ended up scheduling an emergency doctor’s appointment to get to the root of the problem, and her medical team found the culprit.
“What’s happening with me is that the longer I am on immunotherapy, the sicker it’s making me,” the reality star explained. “It’s really hit me.”
More positively, Teddi’s doctor found her ongoing treatment has been shrinking her tumors, so she felt empowered to take a temporary step back.
“Why I medically feel so sick is from the immunotherapy,” she continued. “So, we are going to take a little break on the immunotherapy to get my body back feeling stronger and we’re going to do steroids and everything to get me back to feeling like—I can do all the things.”
Indeed, Teddi admitted that the hardest part of her cancer battle as of late has been how her health has impeded on her daily life, including spending time with her and ex Edwin Arroyave’s three kids, Slate, 12, Cruz, 10, and Dove, 5.
“I started out feeling great,” the 44-year-old admitted. “I could do all these things, and I could go to all my daughter’s horse shows and I could stay at my house by myself and I felt really strong.”
The fluctuation, however, has been difficult for the mom of three to handle.
“The hardest part for me has been like, ‘Wow, I can’t do what I did yesterday,’” she added. “Or ‘Wow, I can’t do what I did three weeks ago.’ Or for me today, I’m still shaking and stuff, but I have a lot of energy today.”
