Symptoms worth watching for We recommend paying attention to the following symptoms, as they likely suggest your levothyroxine levels may need to change: A racing heart, anxiety, tremor, sweating, or trouble sleeping, which can mean your levels are too high, either from the absorption change or from weight loss reducing how much levothyroxine you need Returning fatigue, feeling colder, constipation, or low mood, which can mean your levels have dropped None of these is an emergency on their own, but theyre worth mentioning to your GP
