5c. How do co-existent psychosocial, behavioral, and mental health conditions (such as addiction, somatization disorder, and depression) affect the management of levothyroxine therapy?
■ Recommendation
The treatment goals of hypothyroidism are the same for patients with psychosocial, behavioral, and mental health conditions, as for the general population. However, referral to a mental health professional should be considered if the severity of the symptoms is not sufficiently explained by the severity of the biochemically confirmed thyroid dysfunction or another medical condition, or if the mental health condition is impairing effective management of levothyroxine replacement therapy.
Strong recommendation. Low-quality evidence.
Discussion of the clinical literature
Underlying mental health problems, such as depression, personality disorders (e.g., borderline personality), and addictions, may complicate treatment of hypothyroidism and become frank barriers to informed consent and may impact perception of health state and adversely affect rational decision-making capacity. Patients in these categories should have a formal capacity assessment by a mental health expert (e.g., psychiatrist, clinical psychologist or social worker, licensed addiction therapist) to rule out underlying mental health conditions.
One mental health disorder that has been hypothesized to be overlooked in the context of hypothyroidism is somatization disorder, which warrants evaluation and possible treatment by a mental health professional. Somatization disorder involves a range of physiological sensations and complaints manifest in response to a complex psychological or abuse history (246–249). It is not a factitious disorder or malingering. It has been hypothesized that patients with somatization disorders, who have been treated for hypothyroidism, may persistently complain of a range of symptoms associated with hypothyroidism despite normal laboratory testing (250). Such patients are typically driven to a range of multiple practitioners, who may do multiple work-ups, and even unnecessary procedures. Such patients are frequently at risk for a range of iatrogenic harms, such as risks from unnecessary surgeries. They may also pay large sums of money for nonstandard alternative therapies to deal with their physiologic complaints in an attempt to “prove” they are real (as to the patient, they are), and they may become belligerent and combative when told they are euthyroid. Patients with somatization disorders are frequently misdiagnosed and mismanaged and have complicated medical histories. Frequent misdiagnosis may occur because they seek out so many subspecialists. Somatization disorder is overwhelmingly diagnosed in females, with current hypotheses that it may be a disorder of affect regulation (251) or a complication or manifestation of a history of physical or sexual abuse (252). Recent data suggest that one in three women worldwide have been sexually or physically abused in their lifetimes (domesticviolencestatistics.org). Somatization disorder should be managed in conjunction with a mental health care provider to rule out other underlying psychiatric problems, including personality disorders.
In patients with persistent complaints of hypothyroidism as well as chronic pain and malaise, all organic causes should be ruled out, followed by referral to a mental health practitioner to screen for somatoform disorder. Patients suspected of somatoform disorders should be provided with sensitive discussion in which the referral is explained, in which trust is maintained. Patients should understand and appreciate that their symptoms are not factitious and are real and they may have causes that are rooted in psychological trauma, rather than an organic problem with physiologic causes.
********************
These are my observations.
I am not saying that there is no such thing as somatization disorder, but I am saying that this gives doctors who insist in undertreating their patients a convenient excuse.
The Guidelines fail to provide a clear description of what it means to have met part (i) of their stated goal for treatment (to provide resolution of the patients' symptoms and hypothyroid signs), and the second half of part (ii) (with improvement in thyroid hormone concentrations):
Levothyroxine replacement therapy has three main goals. These are (i) to provide resolution of the patients' symptoms and hypothyroid signs, including biological and physiologic markers of hypothyroidism, (ii) to achieve normalization of serum thyrotropin with improvement in thyroid hormone concentrations, and (iii) to avoid overtreatment (iatrogenic thyrotoxicosis), especially in the elderly.
Instead, the guidelines imply that any doctor who gets his patients' TSH within the lab range has successfully done his or her job.
