Hello Doctor, I'm Concerned About My Sister. She's 48 Yrs

Hello Doctor, I'm concerned about my sister. She's 48 yrs old and for years it appeared to be addicted to eating ice. For the last five days she hasn't eaten any ice. Now she feels feverish inside her body but not sweaty. We're wondering is this part of menopause or something else. Thank you in advance for reading my question
