Feeling shaky and weird often stems from stress, anxiety, dehydration, low blood sugar, or too much caffeine, triggering adrenaline or energy depletion, but it can also signal underlying issues like infections, thyroid problems, or heart arrhythmias, so see a doctor if symptoms are severe, persistent, or accompanied by confusion, severe headaches, chest pain, or vision changes.
Why do I feel shaky and jittery inside? There are a range of possible causes. Some common ones include low blood sugar, low blood pressure, too much caffeine, and dehydration.
Unstable blood sugar levels, especially low blood sugar (hypoglycemia), can cause trembling, dizziness, and sudden weakness. Anemia. Low iron levels mean your body isn't getting enough oxygen, leaving you feeling weak and fatigued. Thyroid disorders.
Explanation. Sometimes you might feel a vibration or trembling all over your body. This can happen when your muscles are tired or when you're under stress. Your body may also react to too much caffeine, certain medicines, or even anxiety by having these little shakes.
However, tremors and other movement disorders are associated with vitamin deficiency, most vitamins B1, B6 and especially B12. B12 is very important for keeping your nervous system in good working order. Severe lack of Vitamin B12 is rare, but shakiness and tremors can occur even in mild deficiency.
B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
Vitamin D insufficiency and osteoporosis. There is evidence that several HKMDs, including Huntington disease, RLS, and tremor, are associated with low vitamin D serum levels.
Five key signs your brain might be in trouble include significant memory loss (forgetting important things or familiar routines), difficulty with everyday tasks, confusion about time/place, problems with language/communication, and noticeable personality or mood changes, such as increased irritability or loss of interest in hobbies, which signal potential cognitive decline or neurological issues.
Certain metabolic conditions, like hyperthyroidism, hypocalcemia, hypoglycemia (low blood sugar) and hypomagnesemia. These are typically treatable. Certain neurodegenerative conditions, like Parkinson's disease and multiple sclerosis (MS). Stroke.
However, a Piedmont neurologist says it is cause for concern if the shakiness begins to interfere with daily tasks like eating, drinking, writing, buttoning a shirt, dialing a phone, etc. In these cases, a visit to the doctor to test for a neurological or underlying metabolic issue may be warranted.
Feeling sick may be a sign that you've fallen ill, but it can also be a sign of anxiety. While feeling sick may be the only physical symptom of anxiety, there are often others including breathlessness, dizziness and fatigue.
Common causes include inner ear problems, medicines, infections, and traumatic brain injury. These disorders can occur at any age. But they are most common as you get older. Treatment depends on the underlying cause and can include medicine, rehabilitation, and lifestyle changes.
Symptoms of hyperglycaemia
Vitamin and mineral deficiencies, including B2, B3, B5, B6, B9, B12, C, D, iron, and magnesium, are among the most common causes of unexplained fatigue. Vitamin D deficiencies affect over 50% of the global population, and approximately 12.5% have iron deficiency anemia.
Common signs and symptoms of low blood glucose
Five key early signs of Parkinson's disease (PD) include tremor (shaking), small handwriting (micrographia), loss of smell (hyposmia), sleep problems (like acting out dreams), and constipation, often appearing years before major movement issues like slowness (bradykinesia) or stiffness (rigidity) become obvious. Other signals involve voice changes (softer, breathy), facial masking, and balance issues.
Dehydration: A drop in fluid levels can lower blood pressure and lead to fatigue and shakiness. Anxiety or Panic Attacks: Stress responses can flood the body with adrenaline, resulting in trembling and muscle weakness.
Trembling or shaking can be a clear indicator of anxiety, especially when it occurs without any physical exertion, manifesting as subtle shakes in the hands or more noticeable tremors throughout the body.
Some of the first signs of a brain tumor may include:
Cognitive Test. Cognitive tests are short, quick tests to check how well your brain is functioning. These tests don't diagnose specific diseases. Instead, they identify a problem with cognition and the need for more in-depth testing.
Symptoms may include:
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
Both adults and infants deficient in vitamin B12 may present with chorea, tremor, myoclonus, Parkinsonism, dystonia, or a combination of these, which may precede diagnosis or become apparent only a few days after parenteral replacement therapy has begun.
