Hello dear,
The symptoms of feeling shaky & jittery during is attributed to easy fatiguability, which can be due to:
1.
Hormonal & metabolic causes like
Thyroid anomaly.
2.
Anemia (either
Iron deficiency or Vit B12 deficiency anemia)
3. Any abnormality in blood pressure & blood sugar levels.
4. Deficiency of certain nutrients like Iron, Vitamin B 12, Calcium, etc. which also interferes with blood formation & nerve conduction.
Symptomatic relief can be obtained with intake of Haematinics & Nervigenic agents along with a healthy balanced diet.
However, the underlying cause needs to be treated.
So, kindly visit your General Physician & get a proper clinical examination done.
Investigations like
complete blood count, estimation of blood pressure and blood sugar levels & Thyroid profile will be helpful.
Wishing you a good health.
Take care.
