Conversely, producing too much of the hormones T3 and T4 can result in the opposite symptom and cause the body to burn through food more quickly. This can result in rapid weight loss, which might sound like a good thing but can actually be undesirable in many cases.
Again, this might be a symptom of other issues – it can even be a common side effect of medications.
However, it is worth considering as a possibility.
The key thing to look for when trying to spot thyroid issues and really any health problem is change. If you previously found it hard to lose weight and it is now falling off, you might consider this a cause for concern.
