Part 1: Looking at the whole body and the root cause.
Determining if there are any physical and chemical factors leading to an imbalance in the body and brain is always the first step. Certain medical conditions can give rise to symptoms that might mimic an unbalanced mood. A few examples: hypothyroidism can mimic a depressed mood, hyperthyroidism can mimic anxiety, hypoglycemia (low blood sugar) can cause anxious feelings, low iron can cause fatigue and low mood.
Also, when your body is deficient in substances like omega 3 fatty acids, vitamin B12, magnesium, vitamin D and overall low protein consumption, this state can lead to the development of depression, anxiety and the like.
Assessing your health with appropriate lab work-up and a look into your diet for possible deficiencies gives me more information to better assess your current health, both body and mind. An appropriate treatment plan can then be tailored for your optimal mood and overall health.
