12 Most Common Graves' Disease Symptoms

2. Skin Thickening

Skin thickening can occur when Graves disease affects your immune system beyond the thyroid. This problem most often appears on the front of your lower legs. You may notice that the skin feels firm, swollen, or raised. The area can look red or darker than your usual skin tone and may feel itchy or tight.

In some cases, the surface looks rough or has a texture similar to an orange peel. Your immune system triggers a buildup of certain substances under the skin. These substances attract fluid and cause swelling, which leads to thicker skin in that area. The swelling often affects both legs, although one side may appear worse.

Skin thickening linked to Graves disease is not common, but it is specific to this condition. It often appears along with other signs of an overactive thyroid, such as weight loss, heat sensitivity, or a fast heartbeat. Eye changes may also occur at the same time. Mild cases cause little discomfort, while severe swelling can make walking uncomfortable due to pressure and tightness.

3. Goiters

A goiter is an enlarged thyroid gland. Your thyroid sits at the front of your neck, just below your Adam’s apple. When you have Graves disease, your immune system signals this gland to work too hard, which can cause it to grow larger than normal.

You may notice swelling or fullness at the base of your neck. In some cases, the swelling is small and hard to see. In others, it becomes clear when you look in the mirror. A goiter does not always cause pain, but a larger one can create pressure in your throat.

You might feel tightness, have trouble swallowing, or notice shortness of breath, especially when lying down. During a physical exam, an enlarged gland can often be felt in the neck. Blood tests are often used to check thyroid hormone levels, and imaging tests can show the gland’s size and shape.

4. Weight Loss

You may lose weight even if you eat the same amount or more than usual. Graves disease speeds up your metabolism, which means your body burns calories faster than normal. Your thyroid makes too much hormone, and this pushes many systems to work harder throughout the day.

Your heart beats faster, your body produces more heat, and you may sweat more than before. This extra activity uses more energy and can lead to weight loss. You may notice losing weight without trying, feeling hungrier than usual, eating larger portions while getting thinner, or having trouble keeping weight on.

Some people lose only a few pounds, while others notice a bigger drop in a short time. Ongoing weight loss can weaken your muscles and reduce strength in your hips and shoulders, which makes daily tasks harder. Continued or unexplained weight loss should be evaluated by a health care provider, especially with symptoms like a fast heartbeat, shaky hands, or anxiety.

5. Difficulty Sleeping

You may find it hard to fall asleep or stay asleep when you have Graves disease. An overactive thyroid speeds up many body functions. Your heart may beat faster, and your mind may feel restless at night. You may lie in bed feeling alert even when you are tired.

Some people wake up often or sleep for only short periods. Poor sleep can leave you feeling worn out the next day. You may notice trouble falling asleep, waking many times during the night, feeling hot or sweaty in bed, or having vivid dreams and light sleep.

Your body may feel tense, and you may have shaking hands, a racing pulse, or anxiety that makes it hard to relax. Feeling too warm can also disturb your rest because thyroid hormone raises body temperature. Ongoing sleep problems can affect your mood and focus, which may lead to irritability, anxiety, or trouble paying attention.

6. Tremors

You may notice a slight shaking in your hands or fingers. This shaking is called a tremor. It often becomes easier to see when you hold your hands out in front of you. The movement is not under your control and can come and go during the day.

Graves’ disease speeds up your body’s systems. When your thyroid makes too much hormone, your nerves become more active than normal. This increased nerve activity can cause your muscles to shake. Tremors usually affect your hands and fingers, may involve your arms, and in some cases can affect your tongue.

The shaking is often fine and rapid instead of strong and jerky. You may find it harder to write neatly, hold a cup steady, or handle small objects. Stress, lack of sleep, and caffeine can make tremors worse. You may notice more shaking when you feel anxious or upset.

7. Sweating

You may notice that you sweat more than usual, even when the room feels cool. Graves disease can speed up your body’s systems and raise your internal temperature. As a result, your sweat glands become more active and produce more moisture on your skin. This sweating can happen during the day or at night.

You might wake up with damp sheets or notice sweat on your skin without a clear reason. Many people report having warm, moist skin. Excess sweating often appears along with a fast heartbeat, nervous feelings, or trouble sleeping.

Higher thyroid hormone levels push your cells to work harder, which creates more heat in your body. You may feel uncomfortable in warm weather, and mild heat may seem intense. Simple activities can trigger sweating. Ongoing sweating may lead to frequent clothing changes and feelings of embarrassment in social or work settings.

8. Frequent Bowel Movements

You may notice that you need to use the bathroom more often than usual. Graves disease speeds up many body processes, including digestion. When your thyroid makes too much hormone, your intestines move food through your body faster than normal, which can change your usual bowel habits.

This faster movement can lead to frequent bowel movements. Some people also develop loose stools or diarrhea. You may feel a sudden or urgent need to go, even when your diet has not changed. These changes can happen along with other signs of an overactive thyroid.

Frequent bowel movements can disrupt your daily routine. You may feel mild cramping or discomfort in your abdomen. Ongoing diarrhea can cause fluid loss, which may lead to thirst, dry skin, or feeling lightheaded. Long-lasting symptoms can also affect how well your body absorbs important nutrients.

9. Palpitation

You may notice your heart beating fast, hard, or unevenly. This feeling is called palpitations. It can happen even when you are resting and not feeling anxious or active. The sensation may catch your attention because it feels stronger or different than your usual heartbeat.

Graves’ disease causes your thyroid gland to produce too much thyroid hormone. These hormones speed up many body functions, including your heart rate. Your pulse may rise above 100 beats per minute without exercise, fever, or stress. You may feel a racing heartbeat, skipped or extra beats, pounding in your chest, or fluttering in your chest or throat.

Palpitations can come and go, or they may last for hours. Some people feel short of breath, lightheaded, or weak during these episodes. A fast heart rate can also make you feel nervous or shaky. In some cases, the heartbeat becomes irregular, which means the rhythm is not steady and may increase the risk of heart problems over time.

10. Menstruation Issues

Graves disease can change your menstrual cycle. When your thyroid makes too much hormone, it can disrupt the balance of hormones that control your period. This imbalance can affect the timing, flow, and regular pattern of your monthly cycle.

You may notice irregular cycles, shorter or lighter periods, missed periods, or trouble getting pregnant. Some women stop having periods for a time, while others find that their cycles come too early or too late. An overactive thyroid can also affect ovulation, which makes the cycle less predictable.

Heavy bleeding is less common, but it can still occur. Any major change in flow, timing, or pain level deserves medical attention. If you already have irregular periods, Graves disease can make them worse. Tracking your cycle can help you notice patterns and changes over time.

11. Irritability and Anxiety

You may notice that your mood changes quickly when you have Graves disease. Irritability and anxiety are common early signs. You might feel tense or on edge without a clear reason. These mood shifts can appear suddenly and may feel stronger than your usual emotional responses.

An overactive thyroid speeds up many body systems, including your heart rate and brain activity. As a result, you may feel restless, nervous, or easily upset. Small problems may seem harder to manage, and you might lose patience more quickly. Family and friends may notice these changes before you do.

Anxiety can also cause physical symptoms. You may feel shaky, sweaty, or short of breath. Your heart may beat faster, which can increase nervous feelings. Poor sleep can make these symptoms worse. When you do not get enough rest, irritability and anxiety may feel stronger during the day.

12. Loss Of Libido

Loss of libido means a reduced interest in sex. If you have Graves disease, you may notice that your sex drive drops without a clear reason. This change can affect both men and women. It may happen slowly or appear around the same time as other symptoms.

When your thyroid makes too much hormone, your body stays in a constant state of high activity. Your heart beats faster, you may feel anxious, and you may have trouble sleeping. These problems can leave you feeling tired and tense, which often lowers sexual desire.

Hormone imbalance also plays a direct role. In women, an overactive thyroid can cause irregular periods. In men, it can lower testosterone levels and lead to sexual performance problems. Emotional symptoms, weight loss, muscle weakness, and heat intolerance can add to the issue and reduce overall interest in sex.
