How does your thyroid affect your overall health?
The thyroid hormones, T3 and T4, produced by the thyroid have many roles in the body. They are responsible for increasing your metabolism, therefore affecting how your body operates in many ways including:
Metabolism: Since thyroid hormones increase your metabolism, your weight, appetite, and energy are greatly influenced by your thyroid hormone levels. When levels are too low, it is very common to have a decreased appetite with an increase in weight, or trouble losing weight.
Hair, skin, and nails: Some of your most metabolically active tissues, such as your skin cells, hair, and nails, are also affected by thyroid hormones as they are replicate frequently. This explains why low thyroid can cause hair loss, dry skin, and brittle nails.
Mind and mood: Like the rest of your body, thyroid speeds up the processes in your brain as well. When thyroid hormones are too low, depression, brain fog, and forgetfulness are common complaints.
Reproduction: Your thyroid hormonal levels are indicators of whether or not your body has enough energy to reproduce or not. Ovaries are also very metabolically active, and therefore hypothyroidism can cause menstrual issues such as heavy periods and infertility.
Cholesterol: When your thyroid hormones are too low, it can cause an increase in your LDL cholesterol, which is a risk factor for cardiovascular disease.
Riboflavin: Optimal thyroid hormones are needed to convert vitamin B2 (riboflavin), into its active form, NAD. NAD is required for numerous biochemical processes in the body, and thus if your thyroid is underperforming and affecting your NAD, there can be a substantial downstream effect in multiple systems of your body.
