Hypothyroidism is a condition wherein the body experiences health complications due to lack of thyroid hormones.
The depleted levels of thyroid hormone can be associated with a problematic thyroid gland.
When a person has such a condition, there are several hypothyroid symptoms that should be taken note of.
Early Symptoms Early symptoms of hypothyroid can go unnoticed because they also mimic symptoms associated with aging or stress.
Some of these symptoms include:

• Chronic fatigue
• Inability to concentrate in an efficient manner
• Inability to tolerate cold temperatures
• Headache
• Muscle pain and joint aches
• Diminished appetite but considerable gain in weight
• Constipation
• Early puberty
• Dry skin
• Irregular menstrual cycle (bleeding can be heavier or lighter than usual)
• Galactorrhea or milk discharge

Later Symptoms As the level of thyroxine levels continue to decline over the next few weeks or months, other hypothyroid symptoms can develop:

• Inhibited mental capacity including the lack to concentrate on things or remember things (this is more prevalent among elders).
  
• Depression - according to some studies, failure in the thyroid system increasing the person's vulnerability to feeling anxiety and other similar emotions.
  
• Weakness in the muscles including cramps, pain and numbness in different parts of the body.
  One thing to take note of is if the person already has an unsteady gait.
  Together with the muscle cramps, carpal tunnel and other similar conditions like arthritis can come up over time.

• Symptoms in Infants and Children

Both children and infants can also experience hypothyroidism.
Thus, it is only necessary to be wary of the condition earlier on to make sure that the condition will not affect their mental development and even their physical growth.
Symptoms for such often rely on how severe and how early the child or infant has developed hypothyroidism.
Some symptoms which can indicate such condition include an enlarged tongue and noisy breathing.
Jaundice or yellowish skin may also be problem associated with early hypothyroidism.
Other more subtle symptoms for infants include constipation, sleepiness, failure to thrive, feeding problems and hoarseness.
