Mama June HOSPITALIZED For Pneumonia

Mama June was rushed to a hospital Friday in Georgia after her temperature went through the roof ... and doctors said she has pneumonia.

Sources close to June tell TMZ ... she was having trouble getting out of bed Friday morning. Turns out she had a 103 fever, so a family member immediately drove her to the ER.

In addition to the pneumonia ... she also had extreme dehydration.

Mama June was at the hospital all day and eventually got some shots and meds ... then doctors sent her home, but told Honey Boo Boo's mom to stay in bed for a few days.

We're told Sugar Bear pitched in to watch the kids while June was getting treated ... and he's gonna hang around for a few days to help out while June is stuck in bed.
