Special Interests

    He will be able to offer consultation and advice to those, who are aged 18 years and above and may requires investigation to rule out hormonal causes for the symptoms mentioned as below:

    Excessive sweating 




    General malaise, tiredness and fatigue 

    Unexplained weight gains or weight loss 

    Menstrual disorder and Galactorrhoea

    Excessive thirst and or urination

    Erectile dysfunction


    He will be able to offer consultation for adults, if symptoms suggest one has any of the following conditions:

    Low blood glucose(Hypoglycaemia):

    Low blood glucose can be diagnosed from symptoms and confirmed by checking capillary blood glucose. The liver is the major regulator of circulating blood glucose in a healthy individual and responds to circulating level of different naturally secreted hormones. Diagnosis of the cause will require blood tests and or radiology imaging ,following which necessary treatment can be offered.

    Sodium and electrolyte imbalance (Hyponatremia):

    Symptoms of low sodium depends on the rate of development of hyponatremia and on the underlying cause. Focussed history, blood tests and  imaging are required to reach a final diagnosis and to organise subsequent management plan.

    Type-1 Diabetes 

    This condition is caused due to destruction of  beta cells of the pancreas, resulting in loss of insulin production. Anyone with Type-1 diabetes will need daily insulin injections, regular blood sugar monitoring. One with Type-1 Diabetes requires regular follow ups with other specialists like Ophthalmologist, Podiatrist and Dietician.

    Type-2 Diabetes and Obesity 

    This condition is a metabolic disorder caused mostly due to increased insulin resistance, without initial loss of insulin production. Though Diabetes and obesity consultants are trained to manage this condition, one would still need regular follow ups with other specialists such as Ophthalmologist, Podiatrist and Dietician.

    Pituitary disorders:

    The Pituitary gland lies deep within the base of brain. Pituitary disorders can be diagnosed from focussed history, blood tests, and dedicated MRI scan of the pituitary gland and following that the best available treatment can be offered. Pituitary adenomas of size more than 10mm may need further evaluation in the multi-disciplinary team meeting with an endocrine surgeon and a neuro-radiologist.

    Thyroid ,Parathyroid and calcium disorders:

    Thyroid disorders are diagnosed from clinical history.It requires measuring blood levels of thyroid hormones and thyroid stimulating hormone, that show whether one has an overactive or underactive thyroid. I investigate the cause to advise  the best available treatment.

    Thyroid nodules and goitre needs US imaging and may need further fine needle aspiration cytology and there after discussion in a multidisciplinary team meeting.

    I will also be able to offer consultation to investigate over active and under-active parathyroid disorders and disorders causing high and low calcium following which treatment can be planned.


    Testicular and Ovarian hormone disorder(Hypogonadism)

    Diagnosis of primary and secondary hypogonadism requires an investigation of the pituitary gonadal hormone axis with blood tests and or radiological imaging following which treatment can be recommended.

    Polycystic ovarian syndrome and Premature ovarian failure can be diagnosed from symptoms and confirmed by blood tests and Pelvic Ultrasound and treated as per protocol.

    Adrenal disorders :

    Adrenal failure or disorders of excess adrenal hormone secretion can be diagnosed from clinical history, blood tests and adrenal radiological imaging.Adrenal nodules found incidentally during imaging are assessed with blood tests, further imaging  and may need input from an Adrenal multi-disciplinary team.
