2. Hyperthyroidism: the patient’s basal metabolism level is higher, the demand for energy is higher, when in the starvation state, the energy supply is not timely, the consumption has more, there may be a starvation, no energy.
3. Anemia: patients themselves have less hemoglobin and weaker ability to transport oxygen, when in starvation, due to lack of energy and insufficient supply of oxygen, it is more likely to have weakness, dizziness and headache, tinnitus, lack of concentration and other manifestations.
4. Diabetes mellitus: the patient’s metabolism of glucose ability to decline, the cells can not effectively ingest glucose, in the starvation, due to the decline in the concentration of glucose in the blood, the cells ingested glucose is further reduced, so that the patient appeared to be powerlessness, dizziness, palpitations, shivering of limbs and other manifestations.
