The thyroid may be a small gland, but its impact on your body is significant. When the thyroid doesn’t function properly, it can lead to a variety of health issues, including hypothyroidism. Hypothyroidism occurs when the thyroid produces too little hormone, leading to a slowdown in various bodily functions. Recognizing the signs early can make a huge difference in managing this condition effectively.
If you’ve been feeling fatigued, gaining weight inexplicably, or struggling with other unexplained symptoms, it’s essential to pay attention to the following signs, which may be related to low thyroid levels.
1. Fatigue
Fatigue is one of the most common and debilitating symptoms of low thyroid levels. Unlike regular tiredness that a good night’s sleep can fix, hypothyroid fatigue feels relentless and overwhelming. People with low thyroid hormone levels often report feeling drained even after long hours of sleep. Getting out of bed can feel like a monumental task, and everyday activities may require extra effort.
This fatigue stems from the thyroid’s role in regulating metabolism. Low thyroid hormones slow down cellular energy production, making individuals feel sluggish, often likened to walking through molasses. As the day progresses, many experience a significant energy dip, especially by the afternoon.
This exhaustion can also come with mental fatigue, causing memory lapses, difficulty concentrating, and a general sense of brain fog. In some cases, these symptoms may be mistaken for stress or depression, but a proper thyroid test can confirm whether the root cause is hypothyroidism.
2. Unexplained Weight Gain
If you find yourself gaining weight despite no changes in diet or exercise habits, hypothyroidism could be to blame. The thyroid regulates metabolism, and when its function slows down, so does the body’s ability to burn calories efficiently. The weight gain associated with hypothyroidism is typically gradual and may come with bloating, especially in the face and abdominal area. This is partly due to fluid retention, another common effect of low thyroid function.
While managing weight with hypothyroidism is more challenging, treatment to normalize thyroid hormone levels can help. However, additional effort through diet and exercise may be required to lose the extra weight.
3. Cold Sensitivity
An increased sensitivity to cold is a hallmark of hypothyroidism. As thyroid hormone production decreases, the body’s ability to generate heat diminishes. Individuals with low thyroid levels often find themselves shivering in temperatures that others find comfortable. Cold extremities, particularly cold hands and feet, are common due to the body’s priority of keeping vital organs warm.
This sensation of being chilled to the bone can affect daily life, making it uncomfortable to be in air-conditioned spaces or to enjoy outdoor activities in colder weather.
4. Dry Skin
Low thyroid levels can cause the skin to become dry, rough, and even itchy. This happens because the thyroid hormones influence skin cell turnover and sebum production. When thyroid function slows down, skin regeneration slows, and the skin produces less moisture, leading to dryness and flakiness.
In some cases, skin may become thickened or scaly, particularly on the lower legs. Moisturizers might offer little relief, and the dryness can cause discomfort. If left untreated, this skin condition can increase the risk of infections or other skin issues.
5. Hair Loss
Hypothyroidism can lead to hair loss, a symptom that can be emotionally distressing. Thyroid hormones are essential for hair follicle function, and a shortage of these hormones can cause follicles to enter a resting phase, leading to shedding and slower regrowth. This type of hair loss is often diffuse, meaning it affects the entire scalp rather than specific patches.
Hair may also become dry, brittle, and prone to breakage. Thinning eyebrows, especially on the outer third, is also a common sign. Fortunately, with the right treatment, hair loss can often be reversed, and hair growth can resume its normal cycle.
6. Constipation
A slower metabolism often causes digestive issues, with constipation being a common symptom of hypothyroidism. As thyroid hormones regulate digestion, low levels can slow the movement of food through the intestines. This can lead to infrequent bowel movements, dry stools, and significant discomfort.
In some cases, constipation may alternate with diarrhea, adding to the discomfort. While increasing fiber and water intake can help relieve constipation, addressing the thyroid imbalance is crucial for long-term relief.
7. Depression
Depression is a frequently overlooked symptom of hypothyroidism. Research suggests a connection between thyroid hormones and neurotransmitter function in the brain, and when thyroid levels are low, this can result in mood disturbances.
People with thyroid-related depression may experience persistent sadness, loss of interest in activities, and feelings of hopelessness. Cognitive symptoms like difficulty concentrating and changes in sleep patterns may also occur. Thyroid-related depression is often resistant to standard antidepressants until the thyroid issue is addressed.
8. Muscle Weakness
Hypothyroidism can lead to muscle weakness, which can make it challenging to perform daily tasks like climbing stairs, lifting objects, or even holding arms up for extended periods. The thyroid hormones regulate muscle metabolism, and when levels are low, muscle function declines.
This weakness can be generalized or more pronounced in specific areas, such as the thighs or upper arms. Some individuals also experience muscle cramps or stiffness, further affecting physical capabilities.
9. Joint Pain
Hypothyroidism can cause joint pain and stiffness, often misdiagnosed as arthritis. This pain is typically caused by fluid retention in the joints and possibly inflammation. Common areas affected include the knees, hips, and small joints of the hands and feet.
Some individuals may also develop carpal tunnel syndrome, characterized by pain and numbness in the wrists. Unlike typical arthritis, thyroid-related joint pain tends to improve with proper thyroid treatment.
10. Irregular or Heavy Menstrual Periods
For women, hypothyroidism can lead to menstrual irregularities. Thyroid hormones play a role in regulating the menstrual cycle, and low thyroid levels can cause heavier or more frequent periods, or in some cases, periods may stop altogether (amenorrhea).
These changes can lead to other complications, such as anemia, and may affect fertility. Women experiencing these symptoms, especially those trying to conceive, should have their thyroid function checked.
11. Slowed Heart Rate
A slowed heart rate (bradycardia) can occur in individuals with hypothyroidism, leading to dizziness or lightheadedness. A normal resting heart rate is between 60 and 100 beats per minute, but people with low thyroid levels may experience rates lower than 60.
This slower heart rate can cause shortness of breath, fatigue, or even fainting spells. If you experience these symptoms, it’s important to consult a healthcare provider, especially if other signs of hypothyroidism are present.
12. Impaired Memory
Memory problems are a common yet often overlooked symptom of hypothyroidism. Many individuals with low thyroid levels experience forgetfulness and difficulty concentrating. The mental fog that accompanies hypothyroidism can affect daily life and work performance.
Unlike dementia, which involves permanent cognitive decline, memory issues related to hypothyroidism are often reversible with appropriate thyroid treatment.
