Mama June's going under the knife to find a safer weight loss solution ... after falling unconscious multiple times.
We're told June is set to go in for gastric sleeve surgery later this month, and hopes to lose at least 80 more pounds. She's been on a crusade to slim down so she'd be healthy enough for the surgery. She's already dropped 90 lbs.
We're told "sleeve specialist" Dr. Michael Feiz in Beverly Hills will perform the operation.
TMZ broke the story ... June was hospitalized two weeks ago after collapsing. Although doctors couldn't pin down the problem, we're told they suspect she was pushing her dieting too far.
