In the initial phases, an underactive thyroid will usually cause the patient to not get enough restful sleep during the night, even if you feel as though you are exhausted. Being that so many people will have a sleepless night from time to time, it is easy to see why this is a symptom that will often go overlooked. However, lack of sleep will keep your body from being able to properly regenerate and you will more than likely wake up fatigued and have a difficult time tackling the day.
Another common symptom of an underactive thyroid is weight gain. With a lot of people gaining weight for different reasons, this is yet another symptom that may go overlooked. However, the weight that you gain due to an underactive thyroid will not go away unless you are able to address the condition that is underlying with your thyroid gland. Only then will you be able to successfully lose the weight.
Have you noticed that you have been feeling cold most of the time? There are a lot of people who have thyroid issues that will say that they feel cold even when others around them are toasty and warm. When your metabolism slows, your body will generate less heat and that can lead to a chill that you will feel a lot of the time.
Another common symptom of an underactive thyroid is fatigue. No matter what type of lifestyle you lead, it may seem normal to you that you will be tired from time to time. This is another reason why some people will get a misdiagnosis when it comes to their underactive thyroid, simply because this is a symptom that can be very common for a number of reasons.
Keep in mind that these are only some of the symptoms of an underactive thyroid. Even if you are not showing any of these signs or symptoms, you still could have hypothyroidism. There are some people who may have only one symptom while others will have a combination of symptoms. The severity of the symptoms will often depend greatly on the thyroid levels being reduced in the blood along with the length of time that the condition has been present.
Even if you are lacking symptoms, you should never neglect treatment for this condition as it could lead to an excess production of TSH, which is thyroid stimulating hormone. This can lead to a health condition that is known as goiter, which can be fatal if it is left untreated.
