A team of doctors or specialists is often needed to figure out the treatment options for each person. [1] Last updated: 8/9/2016 How might limb-girdle muscular dystrophy, type 2C (LGMD2C) be treated? There is no specific treatment for LGMD2C. [rarediseases.info.nih.gov]

The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment. [orpha.net]

Prognosis - Limb-girdle muscular dystrophy- type 2C Patients may also present with elevated CK levels without weakness but with myalgia and cramps, distal weakness, hypertrophic cardiomyopathy, or rippling-muscle disease. [checkorphan.org]

The symptoms are similar to DMD but often milder, and patients are less likely to have mental retardation and have a better prognosis (30-40 years instead of teens). [lecturio.com]

Prognosis and management, therefore, are not uniform across the subtypes of LGMD2. Nonetheless, early identification of complications and risk factors is crucial. [mdfgauteng.org]

Prognosis: Most patients live into adulthood but progression is inevitable and all individuals eventually become totally disabled. Ancillary treatments and support: Respiratory therapy is important when diaphragmatic weakness becomes prominent. [wohproject.org]

Some of the complications can be prevented with appropriate treatment. For example, a cardiac pacemaker or defibrillator can greatly reduce the risk for sudden death due to an abnormal heart rhythm. [medlineplus.gov]

This would entail close surveillance to recognize symptoms and to prevent detrimental sequelae. 2. [pubs.sciepub.com]
