# low BBT could indicate a thyroid issue > **Dr Wilson:** I would say in every case, yes. It is not possible for a person to have symptoms of hypothyroid unless they have a low body temperature. They can have abnormal blood tests and normal temperature and they will still feel fine but the only way you can have those symptoms of hypothyroidism is by having a low temperature.[[(Gustafson, 2015)#^aq9pv]]
